Technical problems (?)

[#1]

Hi, my uploaded Illustrations were rejeceted due to technical problems.

What might that be? Is it a technical problem or the quality of the illustration?

Here a small view … a bigger file is attached.

The defect I see is the missing anti aliassing. But it could also be the "vectorized from a photo" look.

Hm, it said »technical problems«. Then I will try to do a better Design and to have it in vectors or anti aliased. 🙂

Thank your for your remark.
