Hey Frenchkid,
Good stuff!
The cold one is very nicely done, the reds especially. I like the way the purple armor draws your eyes to different spots of the miniature. The base is very bleak and cold looking (which works well)
The purple looks a bit rough and could use a few more layers for transition.
The yellowish color of the cape is too similar to that of your NMM(and a little flat). It becomes more of a focal point than necessary because of the other colors in that area. A layer of more brown may tone that down a bit.
I hope you don\'t think I am being overly critical Frenchkid. I know you, like me, really want to improve in the painting area, I am trying to help, not just critique.
