It's hard to judge a tile in isolation. Make a floor with it. I'm sure some issues will pop out right away even before others take a look, and it'll help others give you more useful feedback too.
For example, this tile doesn't actually appear to tile. The top and bottom boards will have 2px of darkness between them instead of 1px like the rest, and the sides of the boards are cut off, so they're not going to form longer boards across tiles.

You are correct in understanding the wheel, but you seem to have forgotten how your camera works xP

We should see a bit of the rail since the wheel doesn't swallow up all of it.
(I've drawn a 45-degree camera here, but your camera might actually be lower than that, showing even more rail).

The vertical cart looks larger than the horizontal ones. Don't forget that horizontal space is foreshortened, just like on the rails. So, either the vertical cart should be shortened, or the horizontal ones need to be longer (wider).

Where is the light coming from? The shading feels inconsistent.

The dithering may be a bit much, but that depends on the material/texture you're trying to convey. Dithering creates a rough, textured look. Dithering also takes up space you could be using for details and better-defined texture, so that's something to keep in mind.

The sky is usually lighter near the horizon and darker higher up, yours is backwards xP In addition, one of the colour boundaries tangents with the top of the column, making it look attached to the column rather than like a background. In any case, the column appears to be seen from above, so it's not very likely we'd see a sky at all, unless the column's at the top of a mountain xP

It'll be easier for people to give you feedback and avoid repeating themselves and each other if you stick to a single thread.

This sprite has a lot of the same problems as the Batman sprite. The outlines clash and come too close to meeting in some spots, making it hard to read the anatomy. The arms are very long. IIRC Green Lantern's symbol is blocky and should probably be some sort of square or rectangle at this size, rather than a triangle.

I feel like you could make much better use of the available space. Everything is tiny and some of the text is hard to read because of the size, and yet you have all that unused space.

The gold/brass colour doesn't read very well against the grey background, especially for the smaller icons, more contrast between them would really help. Perhaps the grey could be made darker?

The UI feels disorganized. You have four distinct sections (resource list at the top, the circles on the left, the blueprint area in the middle, and the hangar on the right), and there's no clear indication of which is the most important at the moment, what's related to what, and so on. The resource list is the only one that has a clear purpose and a clear place in the otherwise non-existent hierarchy - it's unobtrusive and clearly there to be looked at when you specifically want that information. The other three sections all fight for attention, especially the blueprint area and the hangar.

The lack of alignment between elements also fuel the visual chaos. Everything's anchored to different points, so it appears as though every element is floating independently.
The hangar is a good example of alignment creating visual groupings - the three ship info cards are aligned and have the same size, so despite the spacing between them, they clearly read as related. The L2 and R2 button prompts are aligned with the edges of the cards, so they also feel related, but because they're smaller and simpler, they also feel less important than the ships and don't clash with them. Size/contrast issues aside, the hangar's good! You should try to apply the same principles to the UI as a whole.


Try to avoid having different icons for things with similar functions. The hangar has tiny white arrows for flipping between pages, but the blueprint has large brass arrows, even though those arrows perform roughly the same function (presumably, they flip between different blueprints). Even though the purpose is clear in both cases, it feels less unified and more chaotic. It could also cause confusion if e.g. the player makes the guess that one type of arrow represents inactive/unavailable pagination.
Similarly, some of the ship circles have highlights, and some don't, which can be misinterpreted as meaningful.

In the circle bar on the left, you have a large green sphere next to one of the big circles. Is that the currently highlighted ship, or...? The green sphere looks a lot like the resource icons. It also doesn't feel thematically connected to the ship-circles, perhaps show selections by changing the circles, e.g. by giving them a brighter frame or a different background colour within the circle?
