Not much wrong if you' re just talking ' a little too short.' Like a half inch or so. In fact, I' ve done very good shooting with a bow that draws just slightly short for me.

But when it gets to being an inch too short, then you will start having to get into a cramped position to shoot it. Your form will go bad, your accuracy will be terrible. If it gets to the point where it' s 2" too short, there is a very good chance of injuring your shoulders or bow arm elbow.

I am in complete agreement with AKDoug. If you can get a bow that will grow with you, especially for the same money as the one you' re looking at, you' ll be far better off in the long run.
