It's not that I don't like it it's that it looks worse than it has to. Things get accepted into the gallery in part by the users voting it in, and I don't see this getting in like it is now because of what I listed below. Just something to think about.

 It's not meant to be straight up pixel art. There would be no use for it in a game. It's more just minimal art, that happens to be pixel art. It is more suited towards a wallpaper or something, but since it's pixel art I figured I'd upload it here. Sorry you don't like it. ;)

There's a few problems with this..

Firstly it's uploaded in a poorly supported file type, as it has over 17 thousand colors.

Secondly, the canvas is gigantic in comparison to the sprite, unneededly.

Lastly, the canvas is straight white and serves no AA purpose. In fact, because it is white lots of the smaller details aren't easily seen like the dust and the beam because they too are very light.
