We like the high quality look of #3. We'd appreciate if you could expand on this design and make a revision. While the art inside the plus sign is very high quality, it doesn't necessarily reflect medicine or our brand. Please change the design inside the plus sign to something more relevant to medicine, like the ekg/heartbeat line of #2. We'd also like to see the word, "prime", in all lowercase letters. You could also try different fonts. Thanks for the submissions!
