I sketched some Elf soliders from the Silmarillion in the Livestream today!  These are the three armies/peoples to first fight Morgoth around the beginning of the First Age.

1. The one on the left is a soldier from Doriath, a Middle-Earth Sindar Kingdom that’s largely hidden within a great forest, its capital consisting of a massive cave system.  While Doriath Elves aren’t “High Elves” who have travelled to the West before, they’re a force to be reckoned with during the war against Morgoth.  They’re of Teleri descent, so they are very tall and thin, and those of Doriath are adept at fighting in dense woods.
2. The second is an Elf soldier of the Noldor, who comprise many of the most famous Elves in the Silmarillion.  They are proud and daring, and above all else are master craftspeople and blacksmiths, which their armor reflects.  Noldor are shorter than their Teleri cousins, but notably more muscular. This soldier here is wearing dark paint across her eyes to mark her dedication toward defeating Morgoth and recovering the Silmarils, which the Noldor Fëanor had crafted. 
3. The third is a member of the Laiquendi, or Green-Elves. They were a woods-dwelling people who allied themselves with the Elves of Doriath when Morgoth first returned to Middle-Earth.  Unlike more familiar Elves, the Laiquendi were not technologically advanced, using no metal and clothing themselves in leaves and grass.  They were highly secretive, and only participated in a handful of conflicts during the First Age before disappearing from history.
