Clueing for looks

So I tried my hand at coloured realism and when I saw this screenshot from the episode "Sign of Three" I just jumped at the chance. I had a lot of fun doing this even if it did take me a while and I was experimenting. Sherlock's hair.... I had no idea how to go about doing it so I think I tried a million different techniques before finally settling on one I liked just as I was about to finish it xD

Words can not describe how much I love this episode, it's my favourite for so many reasons which is partially why I did this :3

Anyway, critique is appreciated.
