DW Sketch - Exploring

It's interesting how a picture can change while sketching it...
this one started as a picture of Martha and the Doctor trying to use the Doctor's coat as an umbrella and look how it ended.... the Doctor and Martha in some kind of oriental palace

I promise that I'll finish this picture properly, but first I want to get a tablet... I don't want to ruin this sketch!

Ah well... maybe I'll get my coloured pencils to do this one for a change... we'll see

ETA: Ugh, I shouldn't write descriptions when I'm not feeling well *looks above*.... and does anyone see the hand of the Doctor? No, huh? I think I've got to change that....
