There’s no guarantee that you will even be allowed to submit items to Photodune - it’s not an automatic process like other marketplaces, and you need a demonstrated portfolio for approval.
You need to be careful about what you are submitting and where - Photodune is for photography. 3d or artificial images may well not belong there.
It would be impossible for anyone to predict the likelihood of approval without seeing what the submission is.
Most importantly (you’ve been advised this many times before) is to pick a category and marketplace and concentrate on that and that alone - in the last 4 days you’ve discussed logos, vectors, graphics, photography, video animation etc. changing focus daily almost guarantees rejection.
Nothing will replace investing time, patience and respect in fine tuning skills and practical experience.
