Sometimes, I just have to get something to be perfect. This happens the most when I'm drawing, and I spend hours drawing and erasing just one area to get it to look right. Unfortunately, it doesn't always end up being the way I want it to be. It gets a little annoying and time-consuming at times, but I guess it helps on the long run.
But I guess I'm not the only one.
Here's a picture of the monk from Diablo 3 that I've been working on for a while now. I've only finished the gauntlet on one of the hands and also the fighting stick (although I might need to work on that a little more.) I just started working on the belt and I'm not even close to being done yet, so I'll see how this turns out.
