The artistic photos clash with the folksy family tree decoration. Pick one style or the other.

Might work better with different arrangement of photos and possibly wider dark frames.

Kind of like these.

Lose the word sign tree entirely . The arty family photos need a MUCH larger mat and frame. And more of them to make a great statement.

You want the mat and frame that invites you to come CLOSER. .... the framing you have makes the 1/4 face look choked, and your "intent" for them is a bit denied due to that framing. You could TRIPLE the mat size. Then......it's that invitation, telling me this is important. Look at me!

The photos need to be much larger not just the mat and lose the tree it really makes no sense and I love family photos hung gallery style down a hallway.

Although I like the concept (being a long time genealogy researcher myself) I agree with mostly agree with others here about putting the family tree elsewhere and grouping the family photos together. I also like the partial face portraits but would suggest you get more of the faces. If you do want to keep the family tree perhaps painting it one solid color (white, maybe) might make it blend with the photos more. Good luck!
