Hi, I'm not the founder of this project, but you're one of my favorite Merlin artists and I wouldn't want you to miss out...
Anyway, there is a project in process on Tumblr called
Let's Draw Merlin. It's based off of a similar project where many Japanese fans drew a picture of Sherlock from the BBC show,
Sherlock, and put them all together in one collage (and now the current Sherlock fandom on Tumblr is doing their own take on it). It will be the same case with this project: fans will draw the same Merlin picture, submit it, and the founder of the project will piece together the pictures into one giant Merlin collage.
More information is from the source itself:
