the pics aren't horrible to be honest. The eye of the camera is unforgiving, that's for sure. Use your pics as a reference for improvements. One thing is for certain, you need to use the purple wash from GW on this shade, not black. It's too much of a crontrast. some blending of metallics would really enhance this armour as would some highlights to the purple cloth. You said you did, but I think they are too minor since I can't see them. I haven't really painted alot of purple on my figures, but I usually just start with liche purple, purple wash, leviathan purple highlights, super thin, glaze with the purple wash to blend in more, and straight highlight with leviathan purple in a more refined area and less than I did before.... That's just me though! He looks good man, and with a few improvements, he'll be ace!
