David Tennant passing his sonic screwdriver to the new Doctor, Matt Smith
This is probably the most cartoony thing I've posted here, I think Tennant looks ok, but I haven't seen much of Smith. I drew him a little subdued, as I imagine he'll give a quieter portrayal than the hyperactive Tennant.
I know they don't have a Tardis each, and the screwdriver was drawn without reference, but I think this looks ok. But very cartoony
