Well, work commitments have kept my modelling time to a premium recently. However, after a couple of people badgered (sorry) me via PM about how the project was going, I finally set aside a couple of hours to crack on with it. The nose is starting to take shape now, with most of the major surgery completed and just minor refinements needed to get the cutouts looking the part. There is one small groove still to carve, and a small grille to etch. Headlight recesses still need to be done - I haven't tackled these yet as I'm still in two minds about whether or not to try fitting some Express Models lighting. The photos below show the nose in it's current state - I've given it a quick coat of primer to identify areas which need further filling/sanding and to checkout the overall shape of the cutouts.

EDIT: apologies for the poor picture quality, they looked ok on the mobile screen. Will post some better quality ones later in the week.
