Que problemas técnicos seriam?
Quais critérios são usados para avaliar e recusar as imagens???
All are underexposed and not sharpy focused; I suppose you know that including your watermark is not permitted on images submitted to Adobe Stock.
Some of them are purposefully underexposed. The watermark is only in the images here in this forum (low resolution)
unfortunately "purposefully underexposed" does not count in stock photography. Here, the requirement is based on professional photos and not artistic ability.
