#6 is much better with the confetti. You should try to make the confetti using other colors. Also, try the S in BLAST as a lightning bolt, and making Arcade - Lazer Maze more centered under BLAST. Thanks.
OK, on entries 7 and 8 the S should look more like an S, but using a lightning bolt ensignia. These have one too many zig zags. Both ends of the S should be pointed. Also, try making Arcade - Laser Tag a bit bigger, as well as, It's all fun and games. I can't really tell how well the confetti is displayed, but it should be more than just a squiggly line. It also should have definition. Maybe also try adding some spiral type confetti.
