Hi there! I just submitted my entry today and carefully crafted my submission, Kindly check design (#21612641), (#21612640) and (#21612639). I look forward to see your feedback. Thanks!

So my concept it's to simple but something thats 90 % similar is the winner? ok pffff

that is a very childish and petulant reaction. You entered a contest, I didn't like your submission, someone else was more creative than you, you lost....that's life. You have just shown yourself to be someone that would be terrible to work with. Thank you for confirming my choice.
If you want to work in a creative field, BE creative. AND....don't cry if people don't like your work.
