Love the composition - the tin man with the two Toto's:-) Lighting is good but it could stand to add just a smidge more to further illuminate the darker pup and the right side of the Tin Man that falls into shadow. Lastly, the darker colored pup and the tin man appear in sharper focus but the focus on the light brown dog is soft and not as sharp. Use of a higher F-stop would increase the depth of field.
It looks like the focus is on the prop (tin man) rather than the dogs. I would have liked to have seen the dogs sharper (and in focus). Also, the backdrop has distracting light areas (to the right on the sitting dog, top right of frame...). Also, the front of the back drop is exposed showing the floor beneath, which doesn't add anything to the image. This is just nit-picky stuff though, so take it for what it's worth :-) - it's a cute image. 5
The can robot is in focus and the dogs not, give a little more DOF and focus on the dogs first then recompose and shoot. The bottom part is a little distracting with the green spots, rather crop them out.
5 - Mainly for effort/concept. Good potential. More refined crop, especially at the bottom, but mainly the focus - seems sharpest on the tin man, make this much better in my opinion. Perhaps a variation in lighting too.
nice idea... looks a little soft focused (like focus is on the tin man and not the dogs... good use of a dark background. (You might have been able to edit and get rid of the highlights on it... cute dogs...
the focus is too soft for my taste - I would recommend some sharpening using USM - and I would have cropped it to get the seam of the black backgroun out of the picture - great puppies though!
