Rejected logo

Hi guys,

I’ve just got the hard reject for uploaded logo and as long as there are no comments in “hard reject” mails I really need your help to understand the reason… I’m starter and newbie in the market. I’m doing my works in sketch and porting them Illustrator so may be there are some problems here?

Anyway, please have a look at my work and may be it is not okay as well??

Thanks for your comments in advance!

for me this is nice except for the choice of color and color associations red and yellow is not a good choice to make sure that u value your item , present it in the best way for both reviewers and potential buyers …

Hm…thanks for advice! I think you right and I will try to work with palette
