very very nice, i agree with lukeybaby that the last is fab. What an expression of serenity. I like things in simplified colours, i think the sepia works well here.
the idea of the top two are excellent, but i was thinking maybe show your entire hand (including your thumb) slightly wrap around the tiny hands and feet- maybe to kinda give of it a feeling of security? I dunno just a thought.
Good stuff Liquidflight, i enjoy your posts,
cheers!
