Super job!
As someone noted, the hard part is getting the pistol to fit nicely without bending or breaking the thumbscrews on the front.
A good forum for Firefly/Serenity projects is:

Things have slowed down a bit, but just reading through all the info already posted will keep you busy for a while.
There are a couple of members who have made, or are making, their own Browncoats.
They talk about getting the "flair" at the bottom right as a key to getting the look right.
My own collection is most organized at:

Things have slowed down on all the Firefly/Serenity forums.
A lot of the early excitement has died down and many folks have moved on to other collections.
Things have settled into:
folks working on long-term projects,
QMx releasing a slow-but-steady stream of products now that they have the Firefly license to go with the Serenity license,
folks involved in extended universe or fan films.
Far as Firefly fan films, a round-up of ten can be found here:

Some complete, some stalled, some more professional than others.
But it's a way for folks to play in a 'verse that won't likely soon see new material except in comic books and the Companion volume, "Firefly: Still Flying".

Good luck with your projects, you're off to a terrific start,
