Nursery help

Hey ladies. Need some nursery input. We did half the room today but now I can’t decide what to do for the other wall lol. Do I add the triangles over the dresser wall as well or just do a collage wall with shelves in the corner which will be above a diaper style cart like in pics below. Swing will move to downstairs living room. I will be getting more cactus and allow plants to pull the southwest theme in too! But.... HELP

Also, do I leave the dresser to tie in the theme or paint it black or grey wash?
