Very nice:) It has a comicbook feel to it (Angel Medina's work on Spawn for example)
Also, I seem to detect a similarity between the bug and 'Magic: the Gathering' Phyrexians around the Invasion series, while the figure on top of it could almost pass for a compleated human phyrexian( such as Greven il-vec) though that may all be coincidence.
Overall a very moody athmospheric work, I find myself staring at the distant mountains and skies and all but ignoring the struggle going on right in front of me. I like the battlescene a lot but in my opinion it could use a little extra feel of movement.
