Monster Designs

[Leotaku]

Heya,
I've been doing some monster designs for a friend's game, I was wondering if there was any advice you think might help me out? By the way, I'm pretty young, 16. If you think these suck, please go easy on me :p
I know I'm quite outdone around here, but I'd appreciate any help if you think you can offer some on these.:)

I think I was supposed to post these as images, not links, but there's so many, and in total that's about 1MB. So I left them as links instead. Is that alright?

They are pretty good ;). Crits... There are a lot of details, but volumes are not very clear, so the overall is a bit confuse. I would suggest you to create a side light, or top-side light in order to help the volume representation.
I would suggest you also to read Andrew Loomis books, and of course practice every day™. :D

Keep it up!
