One thing to consider. Hope you don't mind. The cheek piece might be a little tall and too bold. With this comes the strong transition line that radiates towards the corner of the buttplate. I think this is often over emphasized. Look closely at the photo of the original. You might scrounge up a few originals, with a high cheek and bold transition line, but as a general rule, I think it is often overdone.
If you wanted to lower the cheek and de-emphasize the transition, it's not too late.
With all this said, your rifle looks great!
