Nice images overall; color seems to be lacking a bit. Focus on the third and fourth shots isn't as sharp as I like, but that is my personal opinion.
Great work overall!

Very nice job! I lke the first one a lot. Seems like the third one could use a little fill flash or maybe a reflector? His eyes are sorta of dark in that one. Is this person taller than you? It seems like the angle is often on an upslant, which has me sort of looking up his nose a little but I like these a lot, very nice composition!
