Picky? Nah. There's always room for constructive critique.
They're just character sketches, which will most likely never be used again.
I doodled the top one while on vacation, in pen, simply for the same of having illustrations of what my character looks like in the RP. When I got back home, I took the bottom design in the first sketch, and decided to re-make it sort of, so that's why there's the same expression.
Some time Ill most likely make a "new" drawing of that armor up there, simply because besides liking how the design turned out, it was fun to draw an armor of that kind. (AKA full plates on EVERYWHERE, legs and lower torso included) Maybe you'll see some rage in there.
On a similar note: Im real lazy, but I have considered doing one of those character expression memes, if only to draw some different expressions. (also handy for future reference)
