Pillow shading is something that paixelartists just find poor technique and borderline offensive to the medium. The public queue voting reflects this so it will be sent back for revision, k.

 And about that pillow shading, I was simply following this turtle shell's pattern,

But I do get what you're saying, that central lighting is a bad way of shading things, so thank you for that info, again, I will remember to avoid them next time.

 I will remember them next time.

Welcome PixelJoint, 3idolon!

Nice animation. I can tell it is crawling.

The shape of the head seems a bit in-organic. The flat sides don't feel natural.

One thing I would like to warn you about - "pillow shading". It is generally not a well recieved practice on this site.
It will show more of your skill as an artist to use a more natural light-source.

There are some great refence materials if you search around on the forums.
Please feel welcome. We want to see you grow and develop as an artist. Keep working at it!
