Like the idea, but not the colors. The J looks a bit too much like a sword. Maybe round them out and soften the edges (corners) on the letters. Thanks.
First one looked like a sword, but this one looks like a pitch fork. Maybe try to keep the letters inside the square with rounded corners. I didn't want everything rounded, just not pointy ends.
#155 is awesome. However I think the long part of the J is too long, so maybe we can start the curve sooner and show more instead of it going outside of the square. Thanks.
