Okay, I don't mean to be rude - but pretty much this;
Your kerning is all off, and it hurts my eye's. I know sometimes you need to adjust it to get it sitting right, but when you need to play with it so much that it's blatantly obvious then maybe it's time to look for a new font, it's not working in your favour.
Also, I'm not sure why your gradient on 'Po' and 'ke' reset. We are programmed to naturally follow what are called "Vectors" - that being elements in which our eyes follow to guide us through a design. It doesn't need to be as obvious as an arrow, but as subtle as the slightest colour change, or the connection between shapes and words. The reset of the gradient distorts this natural flow. I know people are going to sook and uguu about me picking this out, but hey, I've been doing this for a long time - and this is just so you can make your design just that much better.
If you like, I'm open to questions.
Good luck!
