I am still working on additional refinements, but I wanted to get my idea in front of you asap: #17. Pretty straight forward, yet memorable imagery where the text is the actual meat of the burger. Clean and legible for large signage that people can see from the highway, plus a limited color palette for affordable printing and production.
More ideas to follow, but feel free to comment on this in the meantime!
And here is a more abstract representation of a burger: #19. The nice thing about this version (besides feeling more 'Texas inspired') is that it is a perfect circle emblem. So, its versatility for placement onto anything—signage, uniforms, merchandise, etc.—is very high. It will always look good and fill the space nicely :)
And, of course, we can't forget about the possibility of using red/white/blue for the branding: #20.
Also, I added a grunge/distressed layer to the design. This can be easily turned on or off as needed, so you can decide when to use it—such as putting it on t-shirts to give them a cool vintage look!
