Stop doing those.
What is it - ask a panda? You nailed it. You should have been paid for it.
This is a profession - it’s not a - I hope I win so I can buy bread!!!
I don’t go to 3 doctors and say which ever one of you can offer me the best treatment I will pay.
Nor do I go to 3 mechanics or post a competition online for the best solution to fix my car.
Nor do I go on to a bakers forum and ask them for 100 recipes for baked cookies that I want to sell and whoever has the best recipe will win a batch of cookies!!!
Honestly - have more respect for yourself. Is it a good design, maybe, but like this logo iteration and yourself have something in common.
You are better than this. You CAN do it!
