Made with 3d max file includes special effects, but it was never considered.
Unfortunately, your submission is too similar to existing item(s) in our marketplace. Your upload must be a unique concept not based on any existing marketplace item.
take a better background and use some other stuff what make your mock-up unique
You’re going up against extreme competition here. If you look at the top sellers for similar files they are absolutely fantastic. To get accepted you must match their quality and unfortunately I don’t think that your file is quite there.
I agree at your background looks a little pale.
The shadows may be realistic, but they are also a little simple.
The first two images look a little flat. Overall I feel it lacks some depth.
Hope this helps, good luck
A bump map or normal map in that table and paper texture bump wouldn’t hurt either. As of right now it just looks quite plain to me. Also consider putting some props into the mix; pencils, pens, cups, stamps , crap that you find on a desk.
Also as commented perspective could vary too. Perhaps some window blinds in the background or a chair’s headrest would suffice. In other words a good office background.
