Quite nice,good detail,high quality.
But i should say,that i see some spam brushes,on the chest,you could leave it black,without that metal spot.
The head doesn't fit the set,at least needs black hair.
Set needs more color,about 2-3 more ... like titan,azurite,demolition.
And needs highlights and shadows.
All in all - quite a good work for a #2nd set.
6,7/10.
Keep improving man.
