COMPOSITION
The placement of the kids and the vacuum cleaner helps to form a triangle, which makes the composition of this shot strong. It helps the action to stay in one spot, and the eyes don't go meandering around the photograph. The flag in the background is a little distracting to me, because its colors and "shape" demand attention. However, it does add to the "living room' setting which helps ot make the shot funny.
TECHNIQUE
The lighting here is sufficient to allow for adequate detail to show through. The glares on their "faces" and on the vacuum is a bit noticeable, but obviously natural. If you wanted to get rid of it, (I am assuming it is an overhead light), you could put a tissue or paper towel over it to help diffuse the light. The focus in some areas is a bit soft, but the green fo the "aliens' helps to draw attention away from that. For the most part, the colors seem a bit muted. (More in the background than the subjects). Maybe fiddling with teh contrast/brightness or saturation levels would help some.
OVERALL EFFECT
I found this picture very funny. I have often felt the same way about some of my students at times (my son isn't quite old enough yet). If you are finished with them, send them to my house, I have a lot that they can do!!!!
Very funny and creative. I can think of many settings for this idea, but not necessarily better than the one you chose. Although I understand the idea, IMHO it would have been a little better if there were less distracting elements included in the set, such as only the sofa and the table, without the big blue distracting machine, that flared from your lighting in it's medium area, and the flag.
Ha! Another funny shot that made me luagh out loud. I see all the trouble you went through to make this look and stand up as realistically as it does. Funny shot!
LOL. I feel that way myself sometimes. Very funny stuff. Focus and clarity are good, angle and framing/cropping are also good. The glares off the balloons and vaccuum aren't distracting, but quite noticable. I like how they look like little aliens. bet it was fun getting those balloons on his (her?) feet. Good luck in the challenge.
LOL!!! Great idea. Love the green hands and feet! The alien theme works well with the kids doing chores a VERY foreign concept. Meets the challenge well. 9 :-)
