Excellent work! I prefer the version you called "large one like #12". Let's use this one and discard the rest.
To answer to your questions from entry #23, I suppose you understand I can't give an answer until the contest is over.
I also want to make sure you can deliver the design you propose according to the specifications I wrote in the brief. Indeed, can you please tell me if:
1) You will deliver the file in the .AI format?
2) You will deliver i) a black & white version and ii) this colored version?
3) Within the .AI file, you will use a separate layer for each different element (each letter, flamme, heart rate line) so I can change them easily if I have to?
This is very important to me, as it will provide me with some flexibility in case I have to change the design in the future.
Your answer to these three questions is critical to make my decision.
Thanks for your work!
