@ Corpse : I made all of these in one week, last year. So, I  don't think I improved on them, that's true.
@ Kfuchoin : I can do that for the old ones (the mini guys), but I can't do for the new ones, each time I make a new one I post it, because I don't know in advance if I will make more. Inspiration...

amm dude may i make a suggestion???

put them all in one pixel.. is kinda sick watching the new pixel page fuleld with this guys..

i know ou don't make it for bad.. but it get me sick =/

i've seen everysingle one that you have posted

by the way: a diferent pose.. would be cool...

that's cool and all, but you hardly seem to be improving at all between these "avatars"

If i submit  these pictures, this is because i think they are of some interest for other people.
At first they were designed to be used on a website for publishing comics. I designed many more and I am submitting only the ones I think that will be used by other people.
These avatars are the xmen and you can use to make comics, to make greater pixel art.

Dude, it's okay to practice and all..
but you don't have to submit every single thing..
especially when it's all people in the same position, in the same style. And as small as it is..
