You got a real high self asteem, don't change a thing. Your pic looks a littl low on contrast and for a portrait the guys on the wall do clash with the main subject. 6
Not sure about this one...Shadows are a bit harsh on the left side. The flash is slightly harsh in the eyes. A deeper DOF would make the nose stand out less.
Kill it before it multiplies!! Haha! Just kidding. I think the camera flash casts a harsh shadow on the wall behind it and a harsh reflection in the eyes. I don't think the black and white works well here... I'll bet this looks better in color. And the drawings back there are a little distracting.
Without looking at the title, I thought this shot was technically well-done, but another shot of something mildly humorous without really making me laugh. Then I saw the title, and it all came together =D My one suggestion would be to try some different flashes, as the top gets darker and loses my attention.
This is pretty cute. Got a chuckle out of me. I like the angle and framing/cropping, but I think that it needs more whites. Black and white is good, but I think it's too grey. Focus and clarity are really good. Lighting is also good, but up the white levels, that's my only complaint. Cute shot. Good luck in the challenge.
