For a fat guy his arms look pretty ripped... Might wanna back off on the definition there. Might wanna work in some airbrushing lighter colors and variations of pink, kinda looks like he's one color and masked with soot atm. But coming nicely.
Anyways, in more detail what I said was as follows,
Buu essentially doesn't have any muscle tone at all. He is morbidly obese, so if you live in America you can go to the nearest McDonalds and check out some ppl eating there. See if the average person has any muscle definition at all in their arms. Chances are because they are overweight, no they don't. The fat covers any definition they have so it won't show. So the tricep and shoulder definition you have should vanish. It's fine if you want to add wrinkles or what not between his bicep and forearm where it bends (that area does tend to be exaggerated in overweight people) feel free. But other than that, his arms look very healthy when it just isn't the case.
And for the soot in the face remark, you used a pink base color, which is obvious choice for Buu. However, in the attempt to provide any definition it looks like you just stuck to a burn tool (highlight i'm guessing) so there really isn't any color variation at all and it comes out looking very dull. I used soot as an analogy because the blackness of the shading without color variation is kind of what soot would produce taking away any shine. (Buu is a very shiney character BTW, so white highlights are a very good way to go)
If you need any more clarification lemme know. ^^
Can't wait to see how this turns out.
what? no his eyes are almost always closed. Those are the slits that are his closed eyes, and the dot under them is a wrinkle from his face contorting in anger...its fine.
No, to me it looks right all except the bump where his nose would be...its not that big...and ALOT less defined...pretty much like a flat slate with a really small growth...yeah definetly not that defined. Think his cheeks should be just a (very very very) LITTLE tiny bit bigger too, but not by much if I didn't articulate that clearly.
Otherwise...you should be aware that the render does horrible things to your skin, specifically to his face...makes him look like an alien with sunken cheek bones.
Although You probably wont edit the model...his shoulders should be ALOT wider...he might be fat, but he was a buff fat (note the arms, which are realy nicely done btw), not just...fat fat
Otherwise I love it though, if you release it I'll definetly have a reason to actually use a fatbuu model in esf instead of replacing it with evil buu and a super buu for the trans.
Wait I see what Rays saying...but only from a distance...up close (like the picture he posted) I see what should be seen, the closed eyes and the dots for contortion. However in your first pics I kinda see what he's talkin about.
