Nice and simple design!
the armor's nice and simple design definitely gets a plus point :3
but here comes the critique ^^''
the knee protector of his/her left leg (his/her perspective) looks weird (a bit too high and too small) and his/her left foot also seems to be a tad too thin at its tip. The hands should be drawn with more detail rather than with simple sticks, but that's quite difficult to master at the beginning :3
weapon designs are alright, typically for artists who don't often draw detailed weaponry (mostly rectangular shapes and lack of detail) but that's not so important ^^
