I made two covers for my new book

I like the first one more, but then it has only one of the two characters that's going to be shipped with the reader.

Here's the second one. It's not that good but it has both the characters I want to ship.

I know both of them are not that good...... Are any of these at least good enough ? Or should I use a cover shop?

Be honest, it's ok if you think these are not good !
