So fair it OK. I really hope to see a V2 thought as there are some issue and things to be improved on.

Genreal
The knock back is quite week. especial considering the speed of some of his moves
Arial attacks. most of them are quite useless. B neutral being the worst.
You could give him a bit more range with his sword.
Some attacks I would speed up
Second jump needs to be....well...a better jump. in ruins his over all recovery.

Specific moves

A (ground)
Forward A smash: the first attack of is has no knock back. kind of a issue.
Down A smash: I like it. maybe increase the knock back still.
Up A smash: I would increase the length of the vines and speed up the execution
Neutral A: Its good. if you increase the sword length it will be perfect
all of the directional (non smash) moves are great.

A (Areal)
Up A: It eather dose no damage with a small knock back or it will do 999% auto kill....kind of redeculess.
Neutral a: the animation is kinda lazy. otherwise its good.
Down A: I like it alot. maybe increase the execution
Forward A: I like it. it my need refineing thought.

B (ground)
Forward B: is ok. It would be nice if it didn't leave you unable to recover thought. considering it dose lunge forwarder I understand but...IDK it acword. I would maybe even consider revamping the over all execution.
Neutral B: I like the idea but I would have it do some kind of damage or increase in size. I would actually kind of make it like the trophy with a little less power but with the same speed and size.
Down B: I like it. Its kind of like shadows chaos spear. Charge hold or execute. only thin is it seems to have a set hit back.
Up B: IF at all possible I would completely change it. I know a water element is kind of cool to add but over all its acword. If you wanna keep it I would say make it like Foxs IE have it directional. I would kind of get ride of the hop at the end of it to if you take my modification advice.

B (arieal)
Forward B: well. its not a good alternative recovery...it just kind of doesn't work in that respect....its the same as the ground one which as I said....is kind of acowrd.
Nutreal B: I would just change it. Its ackowrd, dose 1%, and hard as hell to us....I kinda don't even know what its suppos to be.
Up Be: (see ground)
Down B: Its cool but its slow as hell and given his second jump is week it isn't practical.

Final smash: its just kinda useless I would change it if I could......It need improvement if anything. Idea. You could do a summon or something maybe. Its just under powered and hard to us. but I see that in most  (hack) smashs

Grabs: I really like the idea. but if the enemy is too close it it fails to grab them. I would defiantly fix that.

Its a bata. I get that. so over all Its WAY better then any other batas I have played. The animations work (its just the moves that need tweaking) Hope this helps and I look forward to your final product and good work.

(sorry for misspellings....theres a reason for the madness and I run spell check but you know. what are ya ganna do. hope its not to convoluted)
