/ic/ - Artwork/Critique

Can I bit advice or tips to improve this please? I have class soon, but I'd like to have some constructive criticism to look forward to. I know the anatomy is wonky (like the foot), but I'm still too bad to get it perfectly.

I'm a beginner (yes, I'm trying my best with the sticky) so I won't be able to make it perfect or improve it dramatically, but any baby step advice would be appreciated, thanks!
