Coolz! This was awesome! :D _

An interesting concept and I applaud you on making the connection between sand and glass-something I always worry about whenever Crocodile faces a person with fire based powers-namely Akainu. However I think Crocodile can only turn glass into sand, not the other way around since you need extreme heat for the process of turning sand to glass.

For some constructive criticism, you use too many repetitions. Pronouns are okay to use along with phrases that don't repeat the name, but still let the readers know who you're talking about. 'The boy with the straw hat' for Luffy. Also, it's important to 'show, not tell', mainly that you should try to avoid adverbs and try to show the readers the scene you're trying to convey.

One more thing, be careful with how you portray the characters. Ace seems a little too soft. Also, Crocodile is flying off the handle too quickly. Crocodile is my overall favorite character, so I get nitpicky with him. In general, he's calm, collected, ready for anything(made the bomb timed just in case someone were to actually cut the wick? Insane.)and acts superior-which he generally is. And for his powers, Crocodile has refined them to the point that the instant it senses impact, it moves to protect him from getting hurt by anything except water.

Please keep practicing. I'm always happy to see someone willing to write Crocodile-or Ace and Luffy. :)
