Joker Photoshop speed test

This was something that at my nephew's home playing about on his brand new 21" Huion tablet. The first sketch is the doodle that I did on his machine and the second pic is the finished rendering that I did at home the next morning using my Wacom Intuos.

What was the aim with this little project? Well, it was - quite simply put - just a speed test; after having done a couple of other pieces in Photoshop I wanted to see just how quickly I could bang something out "against the clock" if I really pushed myself and I was quite surprised by how fast I actually did this... though it's not my best work, it's surprisingly accomplished for something I did in about only a total of 2 hours!
