Cute and good use of a small object, to try and make a person think of a large object. I like the white background, and you have a nice clean focus... The thing that may have made it more interesting would to have been water flowing throw the straw. Nice job! And good Luck!
I like the white background with the blue infront. The contrast is nice, though the white could have been a bit whiter (I know it's HARD to do though) Maybe a little over exposed too... Nice shot though.
