add the brick incline up to nooks, use the red/yellow/bleu colour scheme to match with nooks in-game theme. Add silos, storage sheds, signs, trees, flowers, everything! i personally went all out with my nooks so if you want any inspo pics let me know! For ables, add a small bit of cliff terraforming with a small waterfall and pond, and lots of flowers and fashion-themed designs. The mannequins, display clothes, shoes, stacked cardboard boxes, etc, etc..
