(ignore the idea for the outlines, just something I wanted to try)
I made a rough edit, just messing around..


You can simplify the background a lot by removing colors and detail, you don't really need to use some colors specifically for the furthest buildings.
I'm not saying remove all detail like I did in the edit.. that looks a bit boring unless you have interesting silhouettes.
But having two colors for the furthest background should be more than enough.

Save it as a gif and you can trim away the excessive colors, you might have to fix the palette afterwards though.

You should try making the canvas bigger, it's really cramped.

I think when eishiya talks about form he means the bigger, overall picture, how things are connected to create a recognizable shape.

Don't be afraid to darken large areas, it can help bring out the form better than if everything is evenly shaded.
Especially with some selective highlights to bring out the most important shapes.

Here is a tiny reference, if you google Vordt you can find more.


Look at how dark it is around his head, it really brings it out. Although it's not the best example of clear form.

This is a very interesting discussion.

Ptoing, if you're able to draw objects without seeing or visualizing them, to me it sounds like you're brain is still doing the work, it's just not showing it to you. Or are there other ways to draw things, other ways the brain store information other than visual, like muscle memory.

If you saw something completely abstract for a short duration and then had to draw it, would you be able to?

Yeah, well it's like you put a layer of skin on top of his helmet.
Unless that's the look you were going for, there is no need to follow the shape of the megaman sprite, because he still has a regular shaped head underneath.
