My personal logo has been the same since day one. I really like the design, and how the letters intertwine with each other; the logo itself is still relevant to me. It just needed a bit of modernization. Here’s the before and after.
There is not much difference, right?! Not necessarily true. The lines are cleaner and thicker, there’s more definition to the roundness of the swirls, and I eliminated the black outline, making it similar to the flat art style I see in graphics a lot. Overall I’m pleased with it!
