Hey man, I hope you don't mind, but I went ahead and edited the sprite a little bit. Once I looked closer, I noticed hair lacked highlight and depth, so I added that in. Also made an example of a shaded armor, though the shape is not triangular, like what you were going for(I think you were?). Feel free to use this, ditch it, or perhaps get the picture of what to do(I recommend leaving the hair though, highlights are pretty neccesarry here). Good luck!
