These are some progress pictures, to show how I came to the finished result. All done in Photoshop CS6. I love Harley Quinn, I always got such a kick out of her flamboyant, rediculous ways, so I really enjoyed this! The finished piece was done for the Animation Art Show, an auction for charity next month.
The final line, and a tonal sketch
Block colouring and adding detail
And the final result!
