This was a commission from an old friend, Erika, for her husband John for his birthday : ) This took an awful lot of time, and though I was only offering sketch commissions at the time I hadn't done something nice for Erika in years, and I thought a coloured picture would be better for a birthday present. For anyone else I would have charged an awful lot more, and if it was for a publication a bit more again, but as I've never done any work for a publication... I wouldn't know how much to charge, I'd have to ask my tutors!

So, this took weeks to do on and off, I'm not entirely sure how long, you'll have to ask Erika. The colouring seemed pretty fast to me compared to the sketch and inking, but then the colouring took over twelve hours, so I wonder how long everything else took... I learned a lot doing this too, namely to never draw the inside of a TARDIS ever again. The line work was still quite sketchy, I would have cleaned it up for proffessional work but as it was for a sketch commission I let it go.
