Excelent work Japokskee!!! Those photos can EASILY (and I mean it) could be in any top magazine with the vibrant color, nice lightning and tack sharpness... Now, if I were you I'll try something more, as example, a black background is one choise, using also a "hand model" wearing the watch or writing with the pen could be your next test... Get creative!!!
might have overcooked the praise a little with the "top magazine", compliment, but these are all solid product photos. I hope you don't mind that I referred another thread here to view your images as examples of what to aim for (the thread in question can be found here
Over there you'll also find an example of my rudimentary product photography. I don't often do it, but I can easily take my lighting techniques from portraiture and put them into use. Even with your DIY white background you can easily achieve a back background that Vintahah
suggests with the right strobe techniques. You'll need to pop your SB800 into Auto-FP mode to get the fast shutter sync. Give it a go when you have time.
