1. shat brix, insane quality and i nice use of shading/gradients (whichever one you used)
2. Cllean, simple head, although SOME sort of add on to the massive blackness :c
3. Very nice, love the way you did the flames, although i think you should have a bit more under the hands since particles normaly go from all around the body part.
4. Another great one, although i think it feels like it could use more detail or something, i jut can't think of what to add .-.

Over they are all great, love the first one though.

epic bro, I'm no art critic, but these are pro.

If u don't mind im gonna pick the head and see how it looks in-game , because your head have a very nice quality there.

Simple and clean .

I like the tori a lot up thee even your banners could use some work on the flame though other then that keep up the good work unless you're going to give up on your GFX skills past them down to me xD.

Edit:

I saw the head in-game it looks pretty outstanding

1. Awesome job. Good shading. But you forgot about the breast. But still, looking good [9.8/10.]
2. I don't really like it cause the lines are too simple. The tongue is very, very strange. I think that took you not more than 25 minutes. It could have been a great head if you would work more on it. [4/10.]
3. Now that's awesome. But only 1 thing i don't like, the flames. Its just some pen tool work, made one shape,copied it and put it on another with changing the color dodge. Pretty sneaky i should say. And the blurred part is quite strange to me. [8/10.]
4. This one is pretty good too, but the blood is a bit... egh... Well I think you know what I mean. [8/10.]

Over all, you can do a lot better, then that, especially to your critique style. I ain't saying that your dumb at art, or even close to that. Maybe you just don't have enough time to work. But you can totally make better than that.

1. nice, its amazing what a single click of a soft brush can do as shading hey? :P but generall nicely done

2. head... bleh... not a fan, similar concept to odlov's first set, but without the flare its had =/

3. nice concept, used a very similar style for my toribash mafia entry(godfather ftw) tho i do think the shading on the side of the head should be removed, seeing as there are flames on both sides of the head.

toris right arm is brilliant.

4. boring in comparison... same style as #3, but without the relevance to the concept. looks rushed.

I'll take all your advice into account for the next time I do something in the style of three and four.

The head was my first in awhile, and I did it for free (I didn't spend much time on it). More of an excercise in mapping than anything. However, I thank you for the advice, and I'll act on it if and when I make another texture.
