well its an awesome design. but there is a thing i need to mention. while bringing so much detail in the armor for example, and not pushing the contrast too far its hard to grasp the design visually. one thing surely is the lack of contrast (the lines dont count.. they do their thing to the confusion) but i think your lines could use some widthrange. do make it easier to differentiate between armourparts, sections of the design. to bring depth into your art.
while you have a beatuiful style and a good grasp on anatomy everything looks really flat and not only on the visual aspect.
i hope you thought this is useful and this makes you think about how you can get yourself even better.
