The ribbon looked a bit rugged... for both entry #4 & #5. I don't really like the color combination for no 4. Try to keep the design simpler as we want to use the logo for product embroidery in the future, so the less stitches it takes, the cheaper it is for us..
For entry #11, 1. make the background white 2. change the "7" color to black 3. make the "Futsal Academy" wording bigger 4. remove the stars from "Futsal Academy" 5. remove the "prison bar" from the crest 6. Change the the ball to a fusal ball (preferablly adidas style) - look at the link: http://images.google.com/images?hl=en&um=1&sa=1&q=adidas+futsal+ball&btnG=Search+images
