So I drew Tirek on paper the other day To be precise, a Tirek based off this fanon http://uglyfun.tumblr.com/post/59326932916/here-is-part-one-of-a-collaborative-my-little-pony
 
My head canon goes that after Sombra was defeated, and his horn sent flying, that it found its original master once more and reattached itself to the remains of Tirek. Tirek quickly came back to life, albeit a tad older than he was and with a renewed hate for Ponykind.
 
A few things with this picture that I dislike I hate how the bag housing the rainbow of darkness turned out and will probably re-design it. I also put in the nose last so I did not have room thanks to doing the eyes first I will fix that when I draw him again
 
What I feel I did well with this picture He looks a lot older and I think I pulled off the balding quite well. I like how his beard, eyes, and horns turned out. When making the bad I decided to replace the string that held the back with a sash to give it a bigger more ruler type look.
 
I plan to build upon this design of an older more grizzled Tirek, maybe slim his muscles down a bit and such. The short fanon comic my design is based off is one of my favorite short comics and I am a big fan of it.
