OH YES, WHOLOCK TIME.
This is what I imagine the meeting of the Doctor and young Sherlock would look like. The Doctor would be all "Look at that bone structure! Brilliant! Want to travel through time and space together?" while Sherlock would just stand there and wonder who let the mad man out of the box.
I didn't do the lineart because firstly, I suck at them, and secondly, I much more enjoy the expressiveness of a sketch. Hope you like it!
