I like this picture and reminds me of monologues wherein there's a picture and a person who's talking in the foreground, using the picture to explain. I also applaud you for the fact that you did this all in MS Paint.
So, let's see in detail!
The facial expressions are pulled off very well, and I guess that some parts of the face were exaggerated, kinda like a caricature, just to promote the "cartoonyishness" in the picture of the person. The fact that you can see his eyebrow is tilted down, wrinkles surround the area near his forehead and his eyes are bulging out just show how angry he is.
The half-mask is supposedly to hide his mouth and part of his nose, but I see you've added the nose, but tinted it the color of the cloth, and added some creases so as to make it look as if it's protruding out. Clever. I just don't see the same with the mouth though, there's supposed to be a faint mouth outline even though he's wearing a mask. The ears are not obvious enough even though their outline can be seen, only half-covered by the mask.
The muscles of the neck kinda remind me of MindChamber's level icon. There's some bare skin underneath just near the chest, but I don't know what it is. Is it intentional? Unintentional? If intentional, is it a fist? A torn part of cloth? What is it? I want to know more!
The hair drawn on the person is smooth, and just slightly tilted, as if to show a wind blowing by from the right. Lighting is appropriately fixed at so that the center of his face is brightest and the parts away from it is duller.
Now about the picture.
The picture in the background shows an open dungeon of a sort, with a cave or a hidey-hole in the wall and part of a monster's head stuck out, and the rest enclosed in total darkness. Unlike the person, the picture in the background is relatively simple, and not a lot of detail is given there, but I can infer from that that it's probably a desert, and was it [not enough detail] intentional?
There's a thought text just outside the background, saying "Hmm..". Interesting....is there a story behind it that I may not know about? All in all, a good picture, and more so that it's done in Paint. I'd love to know what you could do with Photoshop (Or is it fotosheep? :p)
~~ Summary ~~
~~ Good points ~~
1) Nice detail given to character
2) Appropriate lighting
3) Appropriate exaggeration given for cartoony style
~~ Bad points ~~
1) Ears hidden, almost invisible
2) What's that thing at the bottom?
3) Lack of detail for background (Was it intentional?)
