Congratulations. If you are open for (bad) feedback :) take this: Hope you will improve the lighting to be more "stock" orientated. From my experience, artistic photos are not selling very well here. Try a white background. More info about your studio (lights, space) will be good. Good luck.
+1 to Alvera.
Play of light and shadow holds good in artistic forums. Even we photgraphers also like them. But in stock, maximum best selling photos are wellit and most of the subject is in proper focus.
Best of luck with the new studio setup! I understand the joy of having a studio space because I just bought more lights and now I can actually pull of bright well-lit studio shots now too! It's such a wonderful advancement when you've always been stuck with having to use natural light. A few small lights can get decent tabletop shots, but it takes a lot of light to pull off portraits and full body shots. Hope you have a blast and get lots of uploads and sales!!
