A few things I would like to see.
.Ivy & wall/table flora - I love the decorative planters, but would like some greenery I could place on walls similar to shelves, I’ve built a chapel that’s begging to be covered in Ivy. Some vases and urns with flowers would be nice too.
.Chandeliers/wall candles (I like hygge lighting as opposed to overuse of standing torches)
.A white/grey building tier - I’ve noticed most of the building tiers look similar in colour apart from black ice, which is a bit Gothic for me, I’d like something more basic castle looking, perhaps with floor length windows and ornate fences.
.Curtains with physics
.More hairstyles and ability to change them in-game, perhaps learning new styles by reading books hidden around the map.
.Some better top armor for females, the option between bra or bulky armor is limiting.
.Custom wall painting - Take an in-game screen shot and have it painted and framed for wall decor.
