You're the first female composers, I've seen on a forum. Assuming you aren't a 50 year old pedophile... o-O;;
Anyways, I listened to your little piece and it's very relaxing. But if you're trying to emphasize a melody, don't make the other flute overlap the melodic one.... since the higher frequency note usually stands out more. Also, near the ending (third last bar), you use 4ths going down the scale. It sounds too teenage-mutant ninja turtlish =P
Other than that, it's very peaceful. Not too melodic and distracted. Very serene piece.
