Soldier's legs are odd, he looks like he's falling over, the Pyro has a sawblade hovering over his chest that somehow caused him to bleed, you can right click the sawblade with the No Collide tool if that's what you were having a problem with, the over all perspective is odd, it looks like it's focusing more on the Soldier rather than both the Soldier and the Pyro
You'll improve eventually, don't worry
