Background And Cover

Hi there I need two back grounds for my story and I try to search on google but the files aren’t big to use it as back ground ! so i need one with a tree but a special tree there is the link of the tree I want to

so I dont know if it’s possible for create one for me and the second one a forest with a lake just like the background whit the picnic but into a forest.

and I also need a cover for my story : A Life As Not The Others
what i want to see is differents supernatural creatures on the cover (dragon and a wolf)

I know i ask a lot but if it isn’t possible don’t worries I would write whitout a cover :slight_smile: and whitout the background i need (just it will be less real)

thanks for the answer !
