Hey Ake,
Entry 7 is a nice clean logo. I would prefer the letter C be straightened out though if possible. I like logos that are a little outside the box. For instance, where there is something that jumps off of the logo, a color, image, font that is just different from something you would see anywhere else. Keep going with entry 7, id like to see different variations because it is a great start.
I love that you added a new image to entry 12. I would prefer the image be centered though. Something about the image though reminds me of a basketball court, instead of a soccer field.
Your work has been impressing me, so keep it up!
