The answer to that would be yes, things will get better with some time, and gentle handling. The little guy is fresh out of the wild, so his "perception" of you is that you are a giant "monster" that swoops down on him with a giant hand to grab him, and consume him. He will soon learn that he won't be devoured by you, and that he doesn't have to be agressive and try to protect himself whenever you handle him. After a while, you'll notice that the biting, and musking is less and less frequent, and he'll begin to trust you and recognize your scent as something not to be afraid of, this is quite common with very young snakes of many types.
Have fun, and enjoy your new Everglades!
