Since the goal of the pics is to accurately represent your current self for the purposes of attracting clientele, I'd say lose the old pics.
Also, congrats on the weight lost! I've been on that wheel before, and know how tough it can be. 30lbs is a hell of an accomplishment.
Best advice! ^^^Congratulations Jess!
You've always been stunning regardless of change.
But the results ( had a look at twitter ) are dramatic and amazing. I voted for out with the old, for the simple reason, keep them accurate.
