Well here is the colored picture of the sketch I did to illustrate how Arkady's belly and internal testicles will bulge out. Frontally he has one big neck plate and three belly plates, one big and two smaller one. If he has eaten something more or less worthy his size his belly will start to sag and the plates shift apart exposing the greyish tender meat underneath it. Also if the unfortunate morsel tries to struggle hes prints can be seen on the grey soft flesh.

Now to something more personal. I want for the next picture I do improve on 3 more things:

1) Get a drawing tool which is more or less adjusted to the surface tablet I have. Right now I use photoshop which I have from the university but it is way to sophisticated for what I want to use it <.<

2)More consistent proportions of Arkady's body.

3) Overall draw more sketches and upload them into scraps so peps can give feed back x3

Anyway thanks to all which had a look at it! I am always willing to hear constructive critique!
Cheers
