Overspray (the little dots outside the paint stripes) is usually caused by either 1) too high of a psi when spraying or 2) paint isn't thinned properly to allow it to flow evenly. Play with your AB settings including spray distance from nozzle to model, psi, thinner ratios, etc. and you can significantly reduce this effect. Even then, AB patterns will have a fine "feathered" edge vs. a masked or hand-painted hard-edge which sets it apart. As Mark suggests you can also come back along the edges of the stripes with the basecoat and adjust the overspray and blend/fade the camo together that way.
You've got a great start with the stripes and overall pattern, just a matter of practice with your particular AB to fine-tune.
