Yeah. I prefer OCs that look like they could actually be in the show, not ones with like a million hair colors and all kinds of spots or stripes and whatnot. Those kind seem really fun to do because it gives a nice chance to use some different colors of fabric and do some interesting hair styles.
I keep trying to make an OC/ponysona for myself but I can't decide on a body color that I really like for her. I wanted to make her light green, but I have her hair in braids and she keeps reminding me a little too much of young Granny Smith when I have her green. I just can't decide on another color that would go really well with the darker blonde hair and blue eyes that I want to have on her.
