I do sign-- sometimes.

If it's pencilwork, I have no problem signing at all, but when it's digital art where I've CG'd and colored in everything.. I'm a little hesitant about signing it then because I have no idea where to put it! For one thing, if I put it in the corner or whatnot, someone could photoshop it away and steal the work (like anyone would want to, but I'm saying it would be very easy with my pieces), but if I put it directly over the artwork, then it's distracting and I feel the viewer won't get to enjoy the work like I would like them to.

It's something that keeps me on the fence a lot!
