Alpha out the ears! he looks like rather retarded, and annhilates the illusion of harshness and evilness in his face. would you have ears that completly screws up the mental image of the ninja or you'd rather have to alpha it out ( after all, wouldnt it be logical to hide those big tan ears from eyes, after all he must be stealthy n shit, alpha almost everything, but leave some space for a human ear, or some hill of a kind. it's a very good idea of having him to hold a stick with a knife on it, both sides, but make them really look like knifes, you just edit the alpha and added a stick, for a more complete skin, remove the curves and make it knife-like, i know it will look better and have its axis more centered towards the theme.
Now, add more colors to the ninja, he already have those white bands (team color?) and this brown stick.
god i suggest like a belt, im not good with ideas, its your job, im just criticing.
Basicly, you didnt changed the pants, and they could have been changed for significant changes, here it may look like beautiful, but its a considerable lack of creativity/effort; the pleasure of a skinner is when the skin that he took much efforts with it will pay off.
Do more folds, like on the pants you basicly darkened, the shirt you have now, or wathever it is, doesnt look good. i see some folds on his chest, but make way more, and remove that curved-X shaped black thick line out of his chest line, it looks like bold and doesn't have to be here, just put folds over it.
I know ninjas are black, but totally black skins/units aren't very pleasant to see, add more folds, thats my main critic.
I am guaranteeing you more than accurantly that you need folds! they make skins looks like way better when they're wearing clothes, even black clothes have folds, thus lightning and darkening, even if its completly black. try to determinate where the folds might be, so far with the face work, i am sure you can do it, don't say "aw no it looks like fine"; if you say that you're lazy and/or dont really care about your skin. atleast give a try, if it looks bad, well you tried, if you don't try in that kind of situation you will not know.
Well, apart from that, it's somewhat decent, apart from many flaws. but it's one of the best skins i've commented yet ( look at ma sexay 60 comments ), its not a recolor except for the pants ( shame, btw ) and you actually did freehand and even did alpha work! but since you didnt skinned the whole skin, it have still room from creation.
2/5 for beauty (5 or 4 are very very rarely reached, 5 has never been reached). in other words, your skin is decent, some people might use it.
1/5 for originality; the concept of the unit is bad, a high elf ninja? high elves and china ( or relateds) never met together, nor there is no samurais, except for the orcs, that koreans love.
3,333/5 for how much you respected the theme: well yeah, its a ninja, and ninjas wears black, but the huge ears pops out, and ninjas have shurikens. you could have done a warden-like weapon with alphaeing, it has already been done. on this model, i guess you pretty much respected the theme from the typical ninja.
Cheers,
