Superman Returns

Ok well I got my wacom yesterday *yay* and sketched up a picture of Lois and Clark well "Superman" from an image and I had my first attempt at colouring with a tablet, as my attempts in the past haven't been too well full of effort.

I've spent a good few hours on this, and was now hoping I could get some feedback on how to improve it, altho I don't know if I wanna actually change it but I do realise that their lips are funny, but I can't really do everything right

Any feedback would be nice ^_^

I would also like to congratulate on making such a good tutorial for line art
