Aaaahhh...thanks a lot guys. I see what you mean about the AAing and that's something I will have to work on. I also didn't realise about the banding problem.
To be honest with you, I would rather that it would be anatomically correct as much as possible in regards to drawing hands, as that is an area that is important for me to improve on.
I initially wanted to avoid the use of dither, but your idea for the motion blur would work so much better with it. A shadow on the wall for the blurring pie is another thing I'll try giving a go.
As for the leg...I'll try and figure out what's uncomfortable about it and do a retouch.
I'm really hoping I have time to make these valuable changes
Cheers guys!
