Kept my head down while Monsieur won his well-deserved accolades! Meanwhile, for other mere mortals out there who must still walk with wing-blocks and kit engines (they're still very nice, anyway, I think), here's an update on my effort.
The nose tweak is the only new thing I'm contributing to the forum, so I'll concentrate on that.
In the profile view of the V3 fuselage there is a 1mm dip in the line of the upper fuse plane (across a distance of about 7.5mm) just before it meets the nose ridge. I don't believe any such dipping is present with ILM, so I provisionally filled it with white blu-tac. This made the plane flush with the nose ridge, so I built up the rear of the nose by 1mm. This is useful anyway, as my 3mm nose extension requires such a build-up to maintain shape. The effect of this on the overall look is that the fuselage gains in 'forward-assertiveness', something I feel ILM has more of than the kit (this difference to ILM appears not so much in profile, perhaps, but in other combined side/top views).
I'm increasingly certain this is because the canopy and cockpit region of the fuselage are a bit too wide. The front edge of the V3 canopy is 30mm wide. I don't own a V2, but judging from photos, I predicted the V2 canopy front width - which looks closer to ILM to me - would be 27mm. A member here confirmed it is indeed 27mm. Plus, the ILM front canopy edge width and droidstrip width, according to the Red3 and Red1 topshots (and these are pretty trustworthy since the two dimensions are in the same plane) - are practically the same width as each other, with a ratio of 1 :1 in one photo, and 1 :1.1 in the other. The V3 canopy front edge width is 5mm wider than the droidstrip, a ratio of 2.5 :3. The canopy front edge is also a little big in relation to Sat V can width. Thus, the canopy front edge - and therefore the crucial fuselage plane to which it joins - is too wide for the nose, making the nose appear a bit off (to me, at any rate). In effect, what I'm doing with my pulled forward nose is 'restoring' the relationship between the front edge of the canopy and the nose-tip by adding 3mm to the fuselage length to compensate.
Now I can't emphasize enough that the above is no BASH. I love this object - it's my most prized possession, and Mike and Moe clearly remain bestowers of manna from heaven. But I thought I'd share my observations in the interest of the Forum's general drive to perfection... maybe it's all mad and blind BS, but I don't think so...
