[ART] The wine cooler

Okay
LET'S ROCK.
(I really know next to nothing about pixel art, so I'll focus on your illustrationy work instead, k? )

I'm noticing some problems with depth here. This has pretty good depth (apart from the near arm):

but the rest are looking pretty flat. You need to really make your figures seem 3d.
The only advice I can give you is to study from life (I know, I know) and try and use more foreshortening. As it is, a lot of your drawings have a bit of a hieroglyph look; like they're on a flat plane, rather than part of a three-dimensional scene. I am very guilty of this, and really it comes down to just drawing lots, and lots, and lots of figure drawings in poses where you have to foreshorten parts of the body. If you don't have access to life drawing classes, you can always try www.posemaniacs.com , and try drawing from some of the more extreme angles.

Some of your shading suffers the same problem; it looks flat rather than part of a solid form.
This right here is maybe the worst offender:

Trying to show form with cel-shading can be a bit of a pain, since you're not mark-making as you would with a pencil, for example; you can't suggest the form by curving the marks. As such you have to be really, really careful with how you position your shadows.
It's difficult to explain exactly how to fix this; basically it's about how you think about your drawing, more than anything else. Don't think "the chest is quite circular, I will shade it that way" and wing it, try and picture the underlying three dimensional shapes and how the light will interact with them.
Again, this'll come with life drawing. This here is a pretty good way to approach figure drawing with regards to form:

Essentially you're breaking down the whole body into simpler 3D shapes in your head, and trying to make sense of how these shapes interact to make the entire body. While you *are* trying to think of the body in terms of 3D shapes, try not to separate them in your head. If you think "The chest is an egg shape and the pelvis is a cuboid", you might shade them as though they're not connected. For me, it helps to think of parts of the body as simple 3d shapes, but with some fabric stretched over them that softens the transitions between shapes.
I might be talking utter bollocks and confusing you, if I'm rambling, just ignore me and follow the tutorial, yeah?

Even if you're going for a simpler, cartoonier style, understanding depth and form will improve your work like, millionfold.
