Looks good Corelz,
It never bothers me at all if it's painted or stain grade.  I don't have a preference when it comes to paying bills.
Nice work on cutting in the angle pieces. Once they're to short,  there's no going back.

On a side note,  it's more work to paint (lacquer) something than a stain finish.

Figuring out how to do something you have never done is what makes a good challenge.
