Thanks for the kind words Vikes. The project I did using your Ravens logo, turned out to be one of my favorite projects to work on.
As for the Jags design, the project was based on what I thought the team may have looked like had they been part of the 1976 expansion, versus the 1995 expansion. At that point in the NFL, we started seeing more vibrant, brighter colors being used on uniforms and helmets, so that was part of my inspiration for going with the bright blue and yellow/gold color scheme. The logo was designed to look like something from that may have come from that era as well.
