Answer
Not quite enough info to go into what specifically might be causing the bunny discomfort, but it might be experiencing some digestive problem.

I'm not familiar with the tree leaves, but the other things you feed your bunny are perfectly acceptable.  If this is it's normal diet and the vegetables are chemical free, than the rabbit shouldn't be going through digestive problem due to anything new being added.

Fiber is an important part of a rabbit's diet.  A quality hay and pellet will help keep a rabbit's digestive system regular.  If you have some hay, providing hay can sometimes help the rabbit's digestive system work things out.  And the pellets should have at least 18% fiber content in them, with no fruit or seeds in them.

It's very important that the rabbit eat.  You can try inticing it with favorite foods.  And if it will eat vegetables, rinse them with water first to provide extra fluids.  If there is a digestive problem going on, extra water can also be helpful.

A rabbit not eating can get quite serious quickly.  Their digestive systems can start a chain reaction that can be very serious.  If this continues, you will want to take it to a vet and have the vet determine what is going on that is causing it not to want to eat.  Some other things to note for the vet is if the poop has changed in size or consistency, and if the rabbit is pooping less.  Also, if the rabbit is showing any signs of pain like grinding it's teeth, or sitting scrunched up, or if you hear gurgling noises coming from the abdomen.
