I really like this one. It was my inspiration to design the level 3-8 of CP6 (a videogame I made with two friends. You can play it on newgrounds and kongregate).

ow my got now this is a piece of art! :D

I downloaded it and gave it some transparency too see what it would look like. It looks better with the white. The high contrast suits it perfectly.

If you want to add transparency to your future works then download a program called Paint.NET www.getpaint.net/

It's basically MSPaint but with layers and transparency support. Some photo editing stuff in there too 

That's better!

Pixel art does take a long time to do. That's the point!

I don't think it's a good idea to make this bg transparent.

Oh yeah, I forget about the white. :S

But transparency isn't possible because I use paint.

Transparent would still count as a color.

 this is cool, kinda like the stuff i just do draw as a child ^^... but i think you got 3 colors here. make the white transparent maybe
