Some characters? I must say this really looks like the same woman over and over in different clothes.. Your use of colour is gorgeous and these deisigns are visually appealing, but not at all functional as armour if thats what some of these are supposed to be? Some of them look like they might be worn for ceremonies and things but others do kind of say "armour", you know...but if they are in fact armour, they're really just another example of "ah yes this warrior lady is fighting! but she must always look sexy, yes, always sexy...girls must be sexy! even when fighting! yes lets put her in revealing barely-functional armour..yes. she won't even be killed or anything!!!!! being sexy is more important than being safe on battlefield d!!!!!"
And frankly that mindset is reeeally misogynistic and objectifying.
Also I do not know what is happening with this pose, especially her spine and shoulders/neck. And her breasts. Why did you pose her to be sticking them out so much? Did you want her to be sexy???? Anyway, all that aside, these are indeed nice if you ignore all I've said above. The peacock-like design has some lovely colours and texture, the 6th has some really nice patterns. The third design is probably the most functional apart from the breast area, but is still quite nice in regards to pattern and colour choice. :]
I would hardly call some of these designs functional. Several of these designs leave vital organs exposed. The main point of armor is to offer protection to to the body, especially vital organs. Don't get me wrong though, this art is still pretty incredible!
most of them (the ones that don't have a hole in the torso/chest area) are pretty functional, i think. that's why i said i really liked the yellow outfit. though i do think that all the flowing cloth would get in the way of movement.
If I might just pop in here!- The yellow design is more or less functional apart from the uh - chest area. There is metal plating over the breasts, yes, but they trace the shape of the breasts and there is a gap in between them, a piece of metal separating the breasts, and by the looks of it that piece of metal is closer to her body than the "cups". Impact would focus straight onto that piece of metal and has the potential to seveeerely hurt her - bye, sternum! Sorry I just felt the need to uh - sliide that information in, haha..now I'll just kinda fly away !
