Please reduce in size. 2X is OK, 1X better ;)

 ok, im a noobie.... any other tip?

somthing interesting?

I like your work, but the background is a gradient, which is a big no-no in pixel art. I think it would be better if the background was transparent.

Also you don't need to blow it up this big. Actually, you don't have to blow it up at all because this site lets you zoom in on pieces if necessary anyway.

The background is a gradient, otherwise its ok.
