Critique

First let me say loved Matt Smith as the 11th doctor. 
Moving on lol this is a nice set. You have a good variety of croppings
and a variety of placements. This keeps the set interesting.
To take it to the next level,
I think you can play around with textures/stocks.
Currently, there seems to be just model + text.
The text is nice and fitting as well. Play with adding text
via icon textures as well just to see if you like it and try it.
Thank you for this lovely entry!
