Hi, maybe move the larger picture over the bed and taller end tables. I like the wall color.

I'm so sorry for your loss. I would keep the larger painting over your dresser so you can see it while in bed. Place the ones you have of your daughter near each other & do place them near a comfortable chair & side table with a lamp so you can sit there when you need to.

Try to buy a series of prints about 12 X 18 (after matted & framed) to hang about one hand's width above the headboard. Separate each one about 3 or 4 " apart but have them centered above the headboard. You will probably need to use pieces of paper that size to use blue painters' tape to get them centered.

If you do not want to buy any prints you can have family photos sized to fit these or even use pages from a magazine with pictures in them you like. But have them framed & matted. You could even do them larger as in the photo Barbara posted. Fewer frames & mats.

I'm liking the colors you are using & the headboard & bedspread . I also like the large plate you have on the dresser on a stand. You can continue the art onto the other side wall or add a tall beveled mirror framed in chrome to match the nails on the bed. Lean it substantially against the wall.
