My first thoughts were that it looked like a good product shot and had commercial potential - but the triple shadow particularly visible on the calculator spoils it. A soft diffused light top left to get rid of all but the main shadow would make a huge difference. I removed the shadow in PS and it does let the eye concentrate on the other components.
I would like to see an original print. I think that as this would be good commercially - I would think !what is the important part" For me the "texas instruments" text. It seems slightly out of focus and I would get that part pin sharp.
Nice. I love math. Stupid number coincidence, my clock says 11:44 and I look at the photo at the 144 on the calculator. Some people would think superstition or something but numbers are set up to over lap themselves. It's a cycle like everything else. Good photo setup.
