I like what you did. Time is short. Could you try one like #68 with a darker blue shiny colors like those in the top and then change your word" wizard to a shiny gray and see how that looks?
For your efforts, I put you in the top 5 as I feel there is potential with yours. What if we tried one that gets rid of the borders around the words and puts the word fireworks in a rocket and put a fust or a stick out of the rocket where the three lower stars are? We could also also change the grey star up above to yellow if it doesn't mess up the flow.
Great job with #75 and #76. The red looks a bit orange. Could you give it a more metallic look like in the gray. Would it also be possible to see them with some sort of circle something around them to make them more encapsulated like an emblem just to see if it works? I really appreciate all of your effort.
