COMPOSITION
I feel that the composition of this is very strong. You have chosen a good subject, and have concealed your "Waldo" well. Though it is visible, it does take the viewer a moment to "see" it. I also think the tight crop, having the coins "spill" out is also very effective, and adds to the interest of the picture. I think George needs to be lower in the frame though. Right now, his center position (even though he is on the left third) makes it appear a bit static. Lowering, or raising may help that. Also, did you try it with all "heads" up or all "tails" up instead of heads and tails? That may have helped to tie your entire composition together better
TECHNIQUE
Great focus and lighting, the detail of the coins is very crisp and clear, and they are shiny without having distracting glare spots all over the place. The coloring of this is very warm, and it is interesting how all of the coins ended up being the same color. It took a second for me to realize they weren't all dimes!
OVERALL EFFECT
Very nice, indeed. You have met the challenge, and met it well, I think. Overall, a good picture.
I hadte to be the one to bring bad knews to you - some of your money is counterfit. The dimes are not silver, they are made of the same material as your pennies. Opps so are your nickles. Better take them back to the bank. While you are there collect your prize for a fantastic photo of hiding Waldo. Great one - photo and hiding Waldo. Good job.
I like it, One of the few submissions with something to search and find (although it's pretty easy). Like the color, light and reflection. You might have covered the dollar-bill even more. Good luck!
I really like this picture. But, I would have turned all of the coins upside down so that their back side was facing up so that there was only one person in the photo (George). None the less, I like it.
Hmmm that's great but, you should have turned all of the coins upside down so none of the faces aren't showing, and then hidden George's face a little more. But the shot is very good. Good job!
