I just love these markings, I will be attempting them myself in the near future

Nice job on the BMF and a very nice P51.
Just a couple of little things; The gap at the base of the windscreen can be filled with diluted white glue, which will avoid the need to sand.
You also have gap/crack in the port wing fillet and wing leading edge, probably highlighted by the close up shot. It may also be possible to fill these with white glue. If you do it at this late stage, dilute it and apply sparingly. Letting it dry and build it up gradually, to avoid unsightly blobs. You might get away without painting, as the white glue dries clear and it's possible that it will blend in.
Very nice P51, thanks for sharing
