Xenomorph Completion

After approximately 30 hours, the first drawing is finally complete. If I were to redraw the image, there are a lot of things I would do differently from the original attempt (mostly referring to my shading technique), which I consider to be a positive outcome so early into the project. 

One down, 25 drawings to go. For the letter B, I am torn between drawing the Batmobile or a bearded dragon.
