This looks okay to me too but like plateOfFlan said, you can use a damp paper towel and gently run it over the end of the tail in the direction of the scales to ensure all the shed came off. Sometimes it can be really hard to spot stuck shed on tails so it's good to be sure.
Also, it's normal for the ends of their tails to feel stiffer/sharper/pointier as they age! I think the pointy tail actually helps them hold onto things because my ball python will sometimes dig the pointy end of his tail into me or whatever he is holding onto for a better grip.
