Hi Bronto,
No, not too late. Once it's closed up, No one will be able to tell. I am not too worried about the interior.
I try to be as close as possible now but, a long time ago, I had some people who really cut me down or nit picked for the builds I posted ....it took all the enjoyment out of the hobby for me. I mean, I know that is not your intention. I'm just building for my enjoyment and hope others like it too. I used to research until it became a chore for me anymore. If anything, a resin kit or two for the outside where it's more noticible but, I'm not taking them to be judged by IPMS. I'm trying to be more of a OOB guy.
I do appreciate the comments though.
