Ok, it's really bothering me. I can't decide which rune system you are using-- it is clearly not the elder futhark, but it is close. I also can't make any sense out of the text. There are too many vowel in the second line--AAUT SOTT-- and the last 5 runes on the top might be a word for snow--but I just am not sure. Did you just choose runes at random, or did you try to write something--I think they look awesome, though. Runes always make a bow shoot straighter.
thanks for the puzzle.
