It's looking great! I noticed that there are some stain "blotches" on the plywood bead board. This is caused by uneven penetration of the stain. You might experiment with a light, thinned coat of shellac and try staining again. It will help the stain penetrate evenly and prevent the blotches. You can get a "2 lb cut" can of shellac at the big box store and dilute it 50% with denatured alcohol. It should be worth your time for a better look.
If you give the experiment a try, please post pics so we can all see the results.
Keep up the great work,
