I'll save you the mouthful from everyone and direct you here.

EDIT: That's better.

Nice line art!

Here is a thing you can improve on in each image, or keep in mind for future images.
1. It's a little too busy; it's hard to tell what's going on in some places. What's that creature (fox?) with wings doing exactly? Some thicker lines for emphasis could help with this sort of thing.
2. Symmetry! I can see the whole thing isn't meant to be symmetrical, but the body shape should be (the bit that stands out most to me is the shape of the neck/shoulders). Consider even doing some measuring to get it right.
3. From the front, the first two layers make sense, but then the next two layers of the snake's body seem disconnected from them.

Nice linework but there is no sense of depth. It is really difficult to see what is the foreground and what is the background.

As Gaaading said, there's no sense of depth in your art
it's all pretty good though, although personally, I think you would benefit from being a little more stylized instead of only using hard lines.
That's just my opinion though, keep doing what you're doing

I really only got a feel for the second piece of artwork. The other two were fairly well, but just didn't feel complete. The snake one especially was quite confusing, as previously mentioned, because you can't really see where the snake's body really is, where it is all going, or how it is all attached. And for the first one it was hard to decipher everything in the scene because it all almost seemed to be blended together from lightness. Otherwise, keep up the great work!
