Hi Sebastian,
Just a little more feedback for you:
Your font choice for these designs is my favorite, and it is one of the strongest attributes of the designs. On #203, can you please try to use a native unaltered 'X', and then base the end of the arch on the squared-off corner of the 'X'. On the 'Y' end, I think we need to keep the Y's left arm the same height as the right arm.
It going to be tough to decide!
Thanks for your help,
-- Bruce
