The work is interesting.
Maybe some is beter for vector category, no?
Logos need to be more simple. IF a buyer prints B&W your designs are almost lost.
try to submit the Green lamp to vectors category.
It might pass if you add color variations, maybe a cord, a desk…note of paper.
But for logo, yes – it is not ready now.
Sorry to say so.
I myself have many rejected logo ideas – but I have many other interests – not just logos.
