I know that you are easily offended when you get some critique, but to the hell with it.
First off, what exactly is the thing where the text breaks apart in the first work? It looks like.. uhh, I don't know what it looks like exactly. But it certainly is NOT something you'd expect to appear when you break apart such a strong and sharp text. I think pieces of glass or metal or something of the sorts would work far better in that case.
The second work needs more work on the details, for example you could add some pieces of glass flying through the 'hole', and certainly it needs a glass effect for the rest of the work. The way it is now, it appears that a hole in a supposed glass surface appears out of nowhere. You need to add a glass panel on top of it to look more realistic.
The text is also quite bad, change font and put some more effort on it.
As for the fairy tale one, I need to know where you started from to know what exactly you've done. If you've started from scratch, it's quite nice.
The avatar, well, I don't really comment on avatars, they are not exactly the hardest of things to make. The fire effect is not bad, although at some places the editing is very, very poor. For example, the helmet and right above his left arm.
