i like em. i dunno what to say really. they are all so "open" and let you think. i like stuff like that, its not like a boring old portrait or something. even portraits can beccome visually interesting wth a little openess, and i think that you've mangaed to capture that 'magical' value in all of these. the rose is possibly a little too limited (closed) but its still nice.
my favourite is the one of your son, its cool
oh, and i like ur use of black and white, i like black and white
