I like this, the letters are nice and funky simples but i was trying to figure what kind of advice i could give, (even though you did'nt ask...) so I decided to do a rough sketch of it.
same letters, not much of a difference at all but i realized that your line rendering is'nt very confident. It bows here and there and is a little shaky.
If you exercise your line rendering, your letters (which have funk) will hit harder.
