Okay ! Thank you everyone, you helped me a lot ! ^^ Yep, as I said, it's my first map x) . So I try to change every things you mention ^^. There is only the first "cut" that mentioned pixel where I'm unhappy of the result ... If anyone have an idea ^^. Here is the third version of the map ...

It was helpful ! I didn't notice the hook and freeze things, I changed it. Here is the second version ^^ .

Here is my first dummy map ^^. I hope you will enjoy it .
