Excellent geometry based concept, I personally tried to do things out of triangular shapes and know how very difficult it is (I abandonned, not finding a good solution). The result is astounding, as shows your sample.
But I think you should increase the space between words for a better reading. For this you must select a bigger letter width (displacing the green vertical line on the right) for the "space" character than for other letters (you will find Letter Width this button after having selected Advanced then View section). I hope this was enough clear, I am not very good in tutorials and english is not my language, Frodo7 and p2pnut are better tutorialists, ask them if you have not understood my indications.
Anyway, it is a very pleasing first font, welcome to Fontstruct
