cam't see the pic very well, but it looks like you have decent shape and proportions from what i can tell. As you add muscle tone over time you will do well. Try and resist getting on AAS, it will only ruin your femininity.
only about 25% of the members can see your pics! email them to 'gymrat' so he can put them up for all of us to see, you'll get a lot more attention and advice about whether or not you could make it in a fitness comp.
