How did you make you trees ? Be cautious how your elements overlap when you place them or select the option in the layer window to keep transparent pixels intact. or even better, change the mode to background ? (it should be in the first section but I'm usure since I don't have the english version). It will allow you to paint under.
I think your font should be plain, try putting it to bold maybe?
By the way, your background is a little psychedelic.
