Well, i've made all with gimp.
============

Well, they are pretty nice, but one thing I don't like is that on most of the pictures involving a tori, the tori has a really bad quality. It's either blurry or has white outlines, I know that it's hard to actually take a tori out of a picture and still make it look good, but I don't think you had another option in Gimp.
I really liked the gif that you made. It might not be the best looking one, but I like this in/out fade. It looks like something from the 90s games, and I really like old looking things, either gifs or these cutscenes you see.
For the other things...I don't know, they seem just...average, the "Jellyfish" one looks pretty nice, apart from that, I don't see anything to stand out.

Oh, thank you, about the gif, i just don't liked because it was moving too slow and the quality is the worst, but i can say that i've aprimorated the gifs, the only bad thing now is that i cant upload because, it's more than 5mb and the site that i use just accept 5MB in the max.
I should put new gifs, i'm praticing as hell.

All of the avvys were meh, because it looks like you just took a screenshot of him ingame, and then just used the Magic Wand to "render" it. In the first one, you even clipped off the bottom of his hand :/ There was also "gunk" around damn near all of the edges, and when there wasn't any, it was too fuzzy. Take the time to erase all of the excess by hand, or don't expect any major compliments. Everything else just looked like fancy fonts and brushes, with the occasional texture overlay. Meh.

I find a good way to get smooth edges on images is to use the smudge tool with low opacity and smudge the transparency into the image. And they were all meh and you didn't put any effort into them.
