So yea.. Umm.. This was used in a practice session that I've learned.

The blob erasing thingy technique something yea whatever it's called.
Yea, starting with a blob and erasing until a picture comes out, it's pretty fun
Thanks to my loving burr I learned how to do it

Then I further worked with it to practice gradients using nothing but the airbrush tool
and blur brush, Coz Sai doesn't have that cheap gradient bucket :v
I think it came out alright, you judge :3c
