It looks like that web is about 1/4". Pretty thick. You might want to think about thinning that up by dropping the barrel some, particularly at the muzzle. Thick webs often result in a gun that looks "heavy". That will mean you will probably have to re-drill the pin holes, but those plug up easily enough with toothpicks.
Also, be careful about using a rounded rat-tail file for your lock panel sweeps. They generally yield a radius that is too severe. You might think about using something like a half-round file for them, (particularly in the nose) and adjust the radius from there with scrapers. Mostly those radiuses are changing dimension all the way around the lock, so that it looks like it sort of grew out of the stock, rather than having an "applied" look. But again, that varies somewhat based on the various schools of the different builds. Look at lots of originals within your chosen school. Lock panel margins are often a difficult thing that many struggle with for a while before they get it right.
