Wow, surt the walk is very good I agree indeed.

Ok making that Bite and slash more vicious, if i were a bite/slash monster what would I do?

Slash:

Right now hes not slashing it's sort of a punch. Slashing for him would be at the bottom of the claws heres some advice:

Make the slashes come fom a lower angle meaning the place his arm behind him and swinging up at a 45' angle (makingis body turn in the direction of the slash) Don't be shy get up of your chair assume possision and swing a couple of slashes to get the feel and image into your mind. the second slash (if you doing combos) can be more of a uppercut slash fllowing ap fom the initial 45' slash. (really try the actions yourself)

So pretty much:
*Angle those slashes (A couple from the top couldn't hurt either will add to variety of attacks)
*Make the character turn accordingly to display momentum and power
*Get up and feel the motion

Bite:
it looks so slow, (I cant practise a beaatie bit now since I had all my wisdom teeth removed yesterday and my mouth is swollen ) My off the bat suggestions would be :
* Speed it up, make him spring into that bite, sap his jaw and yank back as if to ripp away the flesh of his opponent. (Also requires motion so get up and feel it)
* Also add some form of angle to it.
* Try making him bend down from lower and bite to higher position
* Make it more "snappy" like his really going to bite whatever he is biting OFF!

I can only think of those right now, you are however off to a great start and I do applaud you for your work so far. I love animation and altough I probably crit better than I animate I can't wait to see these improvements!

Best of luck,
