This is a matter of aesthetics.... The 3D shape doesn't quite fully match the picture. I would get around this by "clipping" the fin flash so that it's forward most pointed corner is only on the v-stab part of the 3D model. Shave the lower edge off so that the forward corner just touches the part where the V-stab meets the rounded tail, but that none "bends" if you see what I mean.
It's a minor compromise, but I think it's noticable. Looks odd wrapping around like that.
Also, funny enough the photo looks like the lower surfaces are darker than the upper! See the nose for example, but under the fuselage tail also looks dark. I don't know, you may be correct, but how certain are you of the colors?
EDIT: The panel lines for the flaps under the wings look odd. It's been a while since I admired the flaps on the spit but last I recall I thought they were... "different" ?
