iPod colourisation - dragon

I don't seem to be able to find the pen for my wacom, still so I downloaded this APP on my iPod called sketchbook mobile and thought that I'd try making a dragon sketch into a digital image just to mess around with it the APP itself is amazing and with the zoom of the iPod it does a similar job to a say tablet with a small working area. If you've been following the blog then you may recognise this but I'll post it with this one anyway :).
