Amazing tutorial. It was easy to follow and the results were amazing.
This is only the second tut that I have gone through and completed. I am a complete newb to paint.net and haven't done much with it so far. I am going to try messing around with these effects and see what else I can come up with.
Also, I didn't use the brushes you suggested. I used the same splatter tool that sonicx7171 used in one of theirs because I am just more fond of it.
This is what I came up with.
