I need you to Design my 3 year old boy's room

Design my 3-year-old boy's room. Since we're renting and not owning the place, built-in fixtures aren't ideal. I prefer a modern aesthetic with natural colors, accentuated with touches of blue. The desk you see in the photo will remain as it will serve as my home office space within the same room. I'm looking for storage solutions for his toys that are both tidy and easily accessible for him, as well as a modest-sized bed.
