A lot of really gorgeous movement in this piece. I would have liked to see a bit more work on the arm holding the chainsword, as it seems a little wonky construction-wise, and there is something iffy in how the perspective of the powerpack lines up with the plague marine himself. In your atmospheric depth stuff, you could use a bit more light. Light gets eaten less effectively than shadow by atmosphere, especially any specular highlights or reflections. All that being said, this is still a very enjoyable piece. I shall poke through your gallery and see what else you've got sitting around
