Hmmm... 3 submissions today eh???

wehehe... pretty cool now if only I could keep this up , of course its not realistic but hey i can dream right?

I really should keep drawing no matter what, be it digitally or on good old pencil and paper. I figured your drawing muscles in whatever hand or foot you use, are still muscles and probably behave the same way as every other muscle in your body.
If you use it, it will develop, if you don't, it will atrophy, losing muscle memory, dexterity, striations, mass, whatever.
