Nice. Art is a very personal thing, if you like it then that's all that matters. Print and hang on wall.
My 2p worth though. I prefer things to be more central if you know what I mean. Could always move the centre of your flare thing into the frame a bit more, doesn't have to be on the middle just enough so that the streamer bits go all directions. You could always make you canvas 4x as big and mirror the whole lot down and right, then crop back to a nice balance point?
Just an idea though, looks fine as it is and credit to you for doing it in Fireworks, last time i used it was a good few years ago and it was basic to say the least.
