Your stance is completely horrible. Your legs are too close together, which will make it extremely difficult to stay balanced when taking a hit.

Why does you suit look like pajamas? And more importantly, that's not how you tie any sort of belt.

Standing right in front of a wall, particularly so close to a corner is incredibly stupid. Someone hits you hard enough and you'll bump into it, knocking you off balance and leaving you open for follow ups.

Your hair is a mess, like you just got out of bed. Crap, Man, you just got out of bed in your PJs and decided to take this pic, didn't you?

That is not how you position your arms, offensively or defensively. They need to be tighter, and your hands should preferably be held as fists. Unless you have good grappling skills, holding your hands as loosely as that is completely stupid.

If you're aiming to look intimidating, that's not how you do it. You look like a deer staring at headlights.

… Why am I even critiquing this? This dude doesn't have any idea what he's doing.
