This has to be the least detailed cockpit build I have seen. If like me, (I hope not), I spend almost as much time in the cockpit as I do on the externals (except for a couple of really PITA landing gear assemblies). Given you finishing tallents, this model should be a looker.
All the areas worked over with a file have been wet sanded with 600 than 800 grit, than the entire surface wet sanded with 1500 grit because it had a slightly pebbly texture.
To give an idea of just how small this aircraft was I''ve put it next to first a Sword N-9M I built about 15 years ago and than A B-17C from the zombie shelf
