Started painting about a year ago and I went with the default, box art color scheme because I had no idea what I was doing and was more concerned with learning to paint.

Now that I somewhat have the hang of things, I'd like to make my guys a little more my own. The only problem is, I have all these guys I already painted in the Mars scheme. Should I start over with a custom color scheme, or do something else to set them apart? Or do i just deal with it?
