Pixel Art Backgrounds

Hello,

I made these today, I was planning on using them for my Stencyl Jam Submission, but I decided against it. I am now posting them here, you may use them, but I would like it if you credited me for them.

Also, if you have any feedback, that would be great! I am trying to improve my pixel art, and I think this went well, although I am not to happy with the sky.
