Yeah, I kind of did this in a rush so you will see the lines and so on. Normally, it would be best to draw and paint your original in a much bigger size than 539x316. You can make the dots and sphere's. You just have to do some blurring and other techniques. It's a lot more labor with more layer use so I didn't feel like doing it. C:

Regarding mini-tutorial - yeah, I was considering doing that. I just need to maybe throw in the icons for the tools and maybe show the layers that I used.

What graphic software are you using anyway? I was surprised to hear you say that you didn't use a pencil but the results looked like pencil to me... or where you using MS Paint?
