Need Help with Gallery Wall(s)..

I want to add some color to my living room and went down a rabbit hole of maximalism which introduced me to "gallery walls". Trying to decide between three different options (hopefully the pics help describe it).

• Option 1: gallery wall just above the record cabinets
  • The grey box looking thing on the wall is an in-wall speaker with the grill painted to match the wall. We are considering making that a piece of "art" by re-painting the grill.
• Option 2: pictures on both walls but about the same height
  • The white box on the left is also an in-wall speaker but the grill hasn't been painted yet
  • Ignore the paper taped to the wall, was trying to map out pictures by size
• Option 3: floor to ceiling pictures = go all out and cover the entire walls

Once I decide i plan on adding some pillow covers to help bring some color to the couch as well.
