Yes I did make this. I drew this by hand, inked it with a bic pen, and colored it in photoshop. I then used autobalance and auto levels from the image selection to flesh out the lines, afterwards I colored the drawing and ran it through the cutout filter from the filter gallery in CS3.
I'm actually glad you took the time to look at that stuff. I've seen people portraying other's work as their own and/or not giving proper credit. I'm sure it's extremely frustrating to be on the wrong end of that.
