Looks ok to me. Just keep it clean. Swab with betadine. It will fully heal in a few sheds.
I agree with all this. Don't use triple antibiotic ointment or anything similar, as they can soften and damage scales with repeated use. Silver sulfa is ok to use though.

With snakes, as they heal it looks like it's getting better, then when they shed, all the scabs come off and it looks horrid. But give it time, and as long as you don't see swelling or drainage, you're probably ok.
