Fili and Kili.

"Kili, at your service!" said one. "And Fili!" added the other; and they both swept off their blue hoods and bowed. - The Hobbit, An Unexpected Party.

By far the hardest dwarves to draw. In the end I had to open up my art program on my computer and zoom in on their respective pictures to be able to clearly see their face shapes (why is it that all of their images are either blurry or small?), and only then did it come out well.

Still, I'm very happy with them now, especially Fili. His hair reminds me of a lion's mane.
