/ic/ - Artwork/Critique

Just give me best crit ever. i noticed that giant leg so no need to point out it's size. I also wish i'd be more in the brush touch rather than always using the spray to do my shadings, probably because i'm scared and i only see myself spending one entire week to render one form. There must be a way to breakdown the process of values/shading, can anybody guide me with this? thank you
