NIcely done. I personally just started, but for me this is really cool.

PS. Do you speak russian?

 Do not save as jpeg.  Nuff said.

Looks cool though.

 Sorry, I just started to learn pixel drawing :) That's why )

I liked the lines, but for so many colors?

This is a cool mining unit. I think you did a good job on this, but the color count is very high for some reason. It has 211 colors and there seems to be a lot of them that are so similar you can't even tell the difference. For example, there's one pixel near the top that has the RGB values of 116,124,139 and another pixel right under it that's 117,125,140. What program are you using to make/save these files?
