Hi Gulliver, welcome.
You'll probably want to do something about that pond. It's never going to fit in with anything stuck out there and you won't get the frogs/toads/newts in a raised pond. There may be insect (eg dragonfly/water beetle) larvae in there though so rescue them to a place of safety if you dismantle their home.
The fallen tree could be sawn up to make a woodpile for all sorts of exciting things to live in
