it is possible that the scales under the shed were damaged, i can't quite tell by the picture you posted. you can put some raw unpasteurized honey (regular honey in the bear container won't work) on the area, which helps fight infection because it has antimicrobial/antibiotic properties. if you do this, make sure there are NO crickets in the cage. if there are, they will go straight for the honey and bite your dragon.
i think you will wind up being ok, but there may be others with more experience than i have that see something in your picture that i don't see.
in general, never "help" them shed. their bodies know what to do and will do so if you leave them alone. stuck shed is talked about a lot more than it actually happens. and when it does, it is usually around a toe or the end of the tail.
