Thanks for all your comments.
@Arnaldo & Adam, I know what you mean. I would like to work cleaner and with better quality, but it's not possible. This is going to be ingame- graphic for my own first little adventure-game and it has to be ready within the deadlin of 1 week. It's too much effort to be precise because the game has a lot of animation. The bug we´re talking about is playing in a band. It has 4 other bandmembers. It's a very funny game, dedicated to a nice girl who gave me some inspiration making the game.
Ok, ok, the pixel art its funny But in the artistic terms, This peace don't have quality.
Gotta say this is amazingly adorible! :D And it is quite suiting as your avatar!
