Struggling to design at a bigger scale

What a difference a 0 can make. Jumping from 1-250 scale, maybe 1-500, to 1-2500 is very intimidating. I've tried so many iterations, but its like I scrap my own ideas before I even give them a chance on paper.

Design is a responsibility true, but I can't be afraid to make a decision forever. It's okay to be messy or wrong once in a while.
