The Knoxville Transit Beams asked me to do a logo back in 2015, and the result is below.
In 2019, I revisited the logo. I wanted to make the initials a little more apparent. In the original, the K and B are a bit small and leave the logo feeling lopsided. So I enlarged them and put them behind the figures to add some dimension to the piece. I cleaned up the lines and made the whole thing a little more symmetrical. I also altered some of the line widths just to make Riff and Mag stand out a little more as something separate from the initials.
