Much better! It's improved greatly.
Your tree looks good, I would suggest erasing just a bit here and there of the black outline within, so it doesn't look like stacks of leaves. Also to add some yellowish highlights as leaves go yellow in the sun.
The character could use a brighter face also, as it's a bit difficult to make out. And I'm guessing from the walk cycle that it looks a bit awkward animated? His legs are kicking out to the left and right on the top, which we don't do, and aren't moving very much in the other angles either.
A 3-frame walk cycle can be very effective, but needs to be exaggerated to work properly:
I made this as an example. It's over-done, obviously, but the longer 1st and 3rd frames mixed with the bobbing 2nd/4th frames works very well for retro games. Following this will help you get a better walk cycle quickly.
Good luck!
