@JoshSchouwstra adding "normal sized" objects to show scale is a great idea & gives us a clue as to how large the tree trunk is.
A few suggestions:
- What if the bark were smaller? Would that help add to the sense of scale?
- For me, the sign at the top is what's throwing the scale off and making the tree feel more normal or miniature scale. Do you need it? Maybe the sign over the door is all that's needed?
Just some things to think about. Loving this idea!
