It was tough to get the ambition to do this, I've been somewhat leery of inking for a while and I decided to do this just to get it out of my brain so I could proceed with other works.
I tried a few new things too, I tried a few different basic background colours that would compliment the predominant colour and I think it worked. The tones was the part that probably took me the longest time, there was a lot of messing with brushes/opacity/blending/masking I started off making it really high contrast and then toned it down so I could just see it (and to ensure it didn't overpower the whole piece).
Finally I added some highlights and started playing around with the kind of smokey effect, I thought it looked cool so I kept it!
