Congrats you're in the top 5. Try a few more color variations based on what you have still in the contest. If you have any ideas of improving your design you have only a few days to get it done.
I tried some different colors and messed around with the symbol a bit to make it less like the transformers logo. I think the thing making it look like that is the general shape, if you prefer, I can go back to the original shape with the straight vertical lines wish would make it look less like that. I feel like the diagonals make it more dynamic, but let me know your thoughts.
Something like #225 looks less like the transformers logo and has an implied shield shape, so if you like that one, I could do more exploration with it.
Please let me know if there are any more color combinations you'd like to see. If you narrow it down to the shape/color you like, I can do some different font variations as well.
