I think your sites look great! Really not much to tear apart there. You might want to spice up your sales text a bit, get more in the face of the surfer, be explicit.
Apart from that I believe the teen niche is probably one of the most competitive. Consider branching out and trying different stuff.
100 clicks to sponsor (3000/month) really isn't enough to draw any conclusions from. In the right niche and a good month it could give you 10+ sales. With a competitive niche/poor paysite you could go months without a single sale.
Just stick with it, try new sponsors and niches and the ball will start rolling. Good luck!
