A Roleplay account essentially? This mouse has seen other people do that before actually. DrakeMOhkami, if you're familiar with him, actually has a separate tumblr account for his bunny character where he does something similar to this idea. Mouse says, if you want to go for it, go for it! Though don't put to much on your plate. You already super rarely upload on this account, and adding a second account for RP style art is only going to add more work onto your desk.
