Please help! Hard Logo Template Rejection

Hello everybody!
Please help! All my logo template uploads are hard rejected and they didn’t give feedback/critiques. I need tips how to upload not to hard reject.
They say: “it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.”
Really can’t understand the reason.

To me your logos look close to the standard needed, but they could use some extra polish, some extra care taken to make them look really great. They just look like they’ve been done quite quickly, although the concepts are good.

i like africa travel and rose logo. IMHO that both should get approval

maybe the airplane should look landing on africa continent instead of flying over it
and perhaps use gradient color on the rose logo

just my 2 cents
