Great idea and clever take on the challenge, nice title. Good lighting and composition, the elements play into each other well. The only thing I have is that the boy's eyes are slightly hidden.
This is clever. Cute too! ;^) Trying to figure out the lighting here, looks like a spotlight hitting the beaker and table edge area which is throwing a hard glare on the beaker and really making the white jacket pop out. This in turn makes the white board behind seem underexposed. Not sure how you could have done it differently - a reflector board maybe to bounce some light behind the boy? Anyway, certainly an interesting image to look at. Best of luck to you in the challenge.
with oversized glasses and baggy gloves I would hope for the experiment to be equaly overbearing. Little blown out on the sleave that is up, but is a fun concept.
Nice, I really like this one, parhaps not for the techical control og great composition or stuff like that, but just because it brought a smile on my face and the image has this some sort of good feeling to it.
