I'm still going to tweak 'em a bit for future use, but for now, I have these. Help a fellow Drunk Ducker out?

How about all three? If it's supposed to be a single character popping up then I guess that wouldn't work, but otherwise you could use different color patterns to make it easier for the reader to tell them apart?
Or if it's an entire race, then you could use the markings as a status/class thing...
I don't know, just shooting ideas at a very good design :D

It's hard to pick because the all look great. the one factor I would consider is which design goes with the character you are writing. There seems to be a grin on the first one that could be malevolent. The middle one can be a hero or a villain, the same as the one on the right. It all depends on what you are writing.

Something grobles63 said that made me think about this. The middle one and the right one can't really show much emotion, while I think that the middles one looks better, it would be difficult to express emotion with, since the left one has a clearly visible mouth it would be a lot easier. Maybe you could still use the middle one but make his head coloured the same way as the first one, so you van get the best of both worlds.
