I need some Graphic Design

Hello there

I've seen the contest and I love doing t-shirts. So here is my propositions for the new T-shirts, I actually made 3 models (1 with cowboy had). 2 of the are a little bit more classic and got a nice vintage feel to it but combined with modern coloring and a little bit of a childish feeling to it, and the other one, the one with the star has a CAPTAIN AMERICA feeling to it. If you like them and you want me to change anything for you, don;t hesitate to contact me and please leave feedback so I know if I did any good. Have a nice day and cheers !
