The first one is great. Clean composition and clever use of lines. The second one has great detail, but you could probably use a lower ISO in the future for smoother looking images. Nice work for a start!
Good composition and good focus. #1 will prefer a lower angle shot like #3.
#3, good to diffuse your flash. Good composition and pose.
#2: Nice lighting and good focus on the eyes. Pic abit noisy though.
