Currently my stock photo's are on Shutterstock, Adobe Stock, Dreamstime, Alamy and iStock (but i don't upload new photo's to them, commissions are far to low)
I have tried 123RF, but review times are several months and the rejected my best sellers. So i am already done with them

I'am looking for other sites to upload, wich sites can you recommnd me?

You're on the most popular ones, but there are others. Everyone's portfolio is different, so what works for some may not work for others. But you'll find some other options to test out like you did with 123RF here: https://www.microstockman.com/microstock-photography-sites/

Hope it helps
