It is a nice tutorial , but I like the old one more. I will try this out, and give you my result.
Edit: I will tell you this, it needs to have more shell around it, if you know what I mean. It just looks like an explosion with some rocks around it. As on the other one, it looks like a planet about to corrupt. However, this one is nice because it is 100% Paint.NET, so I give you points for that.
