i considered doing that, but earlier in the thread, people showed interest in making another mlp reference, so i decided not to bother with it. plus, im crap when it comes to rainbows.
i happen to like virizion better for the same reason - cobalion was actually kinda lazy, i didnt even change the original skin tone used. as monochrome said, you can't distinct the colors too much; however, after looking at it for a while and trying to get a different skin color, i sort of saw this lack of distinction as a good thing: winter gives me a very calm feel, almost as if even time itself freezes. most winter colors look all the same with bare/non-relevant changes, and, because of this, i decided to leave it as it was and post it just like that. however, if not everyone agrees, i can try to find a better-looking skin color or even change some other things up a bit (for example, i was considering to give it a bit of green/red, because christmas). the only other thing about cobalion that's the same as the original is the beard, though im keeping that as it is, because i had also tried it black (which is the only other color that'd look good in terms of contrast and would still be different enough) and it look very appealing to me.
regarding virizion, the only problem i had with it after having it done was the contrast between the skin and the main autumn color (wasn't light enough), so i instantly fixed that, just forgot to post it/edit the original post. in any case, i tried to change it up a bit, to see if i got something closer to autumn, as gaunt suggested, though, it ended up looking too much like summer imo.
later, i might also try a stronger/more vivid red-like autumn on the body (see red used in the eye/neck/legs), if the first virizion isn't good enough.
regarding terrakion... this one is being a pain. i spent probably 5 hours trying to find something that would look good on it (mainly the crown-like thing above its head/back), and i still havent managed anything decent enough, not even close to summer. the ps file itself is a mess, it has so many layers with infinite combinations, all of which look really bad, but, in any case, this is what im seeing right now:
orange/red/yellow dont work in any way possible. yellow (only if sand-like yellow) somewhat works on the face/skin, depending on the other colors used. the thing ive changed the least is the main body, which is currently light-blue-grey. and, the worst part of it, or rather, the hardest one to find a good color to is the "crown". again, i strongly welcome suggestions on this one, because ive probably ran out of ideas myself - doesn't matter how "bad" it might look, ill do and post anything you request me to. if im lucky enough, i might come across something that actually looks good. here are some other things i came across before this: http://imgur.com/b1mGZ1P,wWkFpj8,41EXdwl,YDYaOlK,QJloB0Z,FmTLl9b#5
