You can use it as avatar, but it will not be accepted into gallery and will be sent back for revision. Because PJ gallery is 100% for pixelart done from scratch and by hand without effects, filters etc.
its resized yes, mmm its a problem? (im newbie)
I mean, i do pixelart by hand, but i want to keep the same avatar that i made for deviantart, so the people could identificate me if they see me here or there...
(SFME) Sorry For My English
why don't you repixel this logo and make a proper pixel version of it?
