I like alot of white, but not fully bald face (I prefer overos), color around the eyes (not eye liner, but color), I do at the least want eye liner, but if I'm choosing I want full color. And I like blue eyes! I actually prefer one of each, best of both worlds! I think blue eyes are 'easier' to read because they are so clear. There are some bald faces I'm not particularly in love w/, but in generally I don't mind them. And there is a blue eyed horse on dreamhorse that looks like his eyes are popping out, in his (or her, can't remember w/out going back and looking) do seem abit freaky to me.
Now the one thing I don't care for is bald/white faces w/out eye liner and brown eyes, they look to much like rodent eyes. I also don't care for partial eye liner either.
Of the horses ladybugracer posted, I love Bandit and the last horse. Don't care to much for the other two (that second one has the partial eye liner), of course I'm talking color pattern only.
As for the other horses posted (sorry don't want to go through and mention each individually), I didn't see any I dislike!
