Hi and welcome. I have had a look to your gallery and your people images are wonderful and full of quality, Sure that you are a professional and I would say more: A very good professional. I think you will sell good here. Good luck here.
Welcome Johan! The key to success here is diversity. Well, quality too, but from what I can see, you don't have to worry about that :)
Try to upload as many different topics as you can, with just a few variations on the same subject. If a certain subject gets popular, you can focus on it and diversify your offer a little bit later. But at the beginning, select just a few of your best shots from each shooting and upload them, just to see how it goes.
If you get refusals and don't fully understand them, contact us by email and ask for more clarifications. Refusals usually help you to improve, not necessarily your photography, but your selling strategy on Dreamstime.
I look forward to watching your portfolio grow!! Welcome and good luck. I checked out your website. Very nice-I like your style. My tip would be to review the message boards and blogs concerning how you title, describe and keyword your images. It really makes a difference with the search engine.
Currently my primary cameras are a Fuji X-Pro2 and a Fuji X-T2.
