We are a new school, and as a school voted to have the "Spartans" as our mascot. I am looking for a design for our Spartan logo/mascot. This logo will go both on our sporting gear (jerseys, fan gear, water bottles, etc) and also be a part of our logo design for school sign, letterhead, etc. Therefore, I'd like the design to look professional, classic and clean, not cartoony or overly-exaggerated. Also, because of the multiple uses, I'd like to have multiple colorways - in our school blue for light backgrounds, inverted white on blue, black for white backgrounds and white for dark backgrounds.
A few key background pieces of information: we are affiliated with USC (whose mascot is the Trojans) and would like our mascot to look related, but distinct. I would be open to multiple perspectives, but have a hunch that a profile view (similar to USC Trojan) would be preferred. Our primary school color is blue (pantone 639 c); our secondary color is a charcoal gray.
