Is wood movement a concern with this design? Way to improve it? 10" wide kiln dried cherry

I am building a pair of console tables for a friend and they decided they didn't want multiple boards laminated together, but rather a large 10" wide single boards to make up the table. The wood will be 1.5" thick, 10" wide, and joined with miteres at 45 and wood dowels. The longer one (pictured) will have at least 1 vertical support to separate the cubby.
