i must say, the general lineart of the knigth is terrible. from the gravityless belt to these tetacle arms. rather than an armor, he appears to be wrapped with a transparent tape, and this is caused by the color choice. using a diferent color for each segment from his armour doesn't really work, as the use of almost 3 or 4 new colors per ramp on each segment(you can hardly see 2 colors at 1x). i would use less colors but more contrast between them.
