Man that is a huge improvement, the new elements really made the building a volume which is part of the scene. I take back some of my nitpicking on the geometry, as I realized your game is more of a charming illustrated interactive book than a game-space world with geometrically exact collisions and stuff. Your stair is still "incorrect", but it gets the idea across, looks nice and is also consistent with the way many classic rpgs deal with ramps between levels. My game is about  2.d jumping and platforming elements over a tradional rpg perspective, which led me to be too demanding regarding geometry when giving you critique, for which I apologise.

The shadows are enough for a bright day scene, but they could go a little darker.

Alright, thanks everyone, I'll give it another shot and post here!

Ah, with this perspective the broken pillar, which is a cylinder, would either:

1- be aligned with the horizontal axis like it seems to be, and as consequence, the rounded "top" which is tilted sideways on the right end wouldn't be visible, the pillar would end in a straight vertical line on the right side, very much like if it was a 2d platformer game asset.

2- for the circular section to be visible the pillar would have to be aligned diagonally on the x y plane. That would be trickier to draw correctly, but you surely can do it if you want.

Notice the same distortion happens with the second block, the one to the right. If it's shorter side was to be shown, then it would be at an angle and it's outline wouldn't be rectangular anymore, more like a isometric cuboid.

Then again, you are obviously free to take liberties with your perspective, if you do it intentionally

I like him a lot! The only significant problem I see is the lack of contrast between the black and the dark green, which is also to far from the "bright" color. Although the red is not bright in itself, the general color balance has the mid shade too close to the black. Are you on a fixed pallette like NES or GBC? If not I would suggest less saturation to bring the colors closer together, and then set more natural ramp, like a warmer, a bit lighter green for the mid shade, and a more orange-ish red.

I think he is more like a two 16x16 tiles tall creature than a 32x32 object, as that would be  the size of its collison mask in game, the wings would just be overflow.

Thanks for the pointers Meat, this is actually an earlier and less polished "fork" of the portrait with larger and higher eyes, also showing the jaw-line problems, but it so different that he became another person:

Interesting how face proportions are more distinctive from one face to another than the shape of the features. This guy has a way more brutish appearance, but are the proportions and volumes any better compared to the other one?
