Lol, hilarious description! "but.. tits" And hmm, is it bad that the part that I got most excited about was the power balance band? But the rest of the picture looks lovely too (I was just remembering back when I went buying them power bands lol)
This is an excellent sexy composition. You have a very good eye for this. I just wish you had a better camera and proper lighting to have capture this marvelous image better, so it was a more clear image. Even with the camera you have your images will turn out a lot more clear with better color vibrancy if you can get a lot more candle power on your subject. I can see you already discovered how the built in flash does not give you good lighting, so you are relying on nature light from a window, but there are other ways to get a lot of light on your subject w/o using harsh direct Sunlight, which would be around 10X more candle power. Cloudy days outside can give you a better soft lighting, but that is less than 1/2 the candle power of direct Sunlight. Even a cheap tripod can be your best friend, even if you have a friend taking these photos for you.
You should be able to connect with a photographer in your area who you can trust to not pick your pocket, or other valuables. You'll need to be careful though. Many women use modeling as a cover for prostitution, so your shooter may think you are offering a lot more than modeling.
