So...I am making a website where users can adopt their very own Rattus cornibus, Horned Rat. So...I'm practicing my rat anatomy! If anyone is very rat savvy and would like to help me out, just post. I'd be much obliged.
It's when someone draws something (such as my rat) and then a more experienced artist (Seatala, in this case) draws over it, correcting the faults in the original It's a way to help artists expand their knowledge and learn from their mistakes.
