Looks fine to me--very similar to what I'd do with it myself.
Real Model Airplane Guys will have conniptions over your lack of seat belts. Seat Belt Fetishim is quite common in Model Airplane World, for some reason, even to the extent that they have a specific exception in the Out-Of-The-Box rules to let you add seat belts. I am NOT one of Those People, and laugh at their weird fetish, and happily build model airplanes without seat belts all the time. Model on!
