I don't mind your piece at all, it's quite an interesting looking character. I think it definitely has an air of intimidation to it, and i love the medallions and clothing items, overall looks pretty cool.
Background: I feel that the extremely harsh white background and the overall brightness of the piece hurts the image, the whiteness of the background doesn't help give the image a very depthfull look in my opinion. I feel that it's quite harsh on the eyes, and the lack of scenery doesn't help me understand this character.
Line weight: I feel that this piece would benefit greatly from some line weight to the major body parts and clothing items. Some thicker lines for the legs might emphasis the muscle groups outer protrusions, giving a stronger impact, the same with the pec muscles. I'm unsure how thick it should be overall, but i just think some emphasis would greatly benefit your piece.
Posture: While i feel that your current posture exudes a sense of intimidation to it, i think personally that it's quite a dull posture, it does give the character its sense of superiority, but doesn't really allow me to know anything else: what i mean is, by the use of, for example, a slight smirk may give me the idea that your character is overconfident or cocky. A way to allow further character insight would be character sketches.
Overall, it's a nice character, i feel you've done a decent job, you should be very proud of what you've got so far!
