Hey there, here's a late welcome on my part as I've been away a lot XD I'm just a fellow student here,
Gotta say, I like your use of stylized semi realistic heads with flowey contrast between detailed facial features and loose brush strokes for backgrounds and effects
Couple of things i notice in this piece is the perspective on the sword looks off and something about the way the highlight on the nose goes all the way through and the shadow on the figure's right nostril goes too far up, might have to recheck the structure there
cheers!
