Best way to design trees?

I’m working on a solo project (Oh thank god) that I’ve wanted to make FOREVER, but in the early stage of designing, I’m having trouble designing trees. The game is a souls-like but my own style (Then I guess it’s really not a souls like, but whatever), does anyone have any references I can view to make good looking trees? Preferably TWW styled trees, love how the devs did that.
