Hi Stug
She's gonna look neat! :-) It really cries out for some weathering and washes to make the detail pop out!
Do you apply varnish only where the decals are to go? I ask because there's a little shininess still around the decals, while the rest of the painwork is pretty matte. A coat of varnish overall should tie everything together (and make washes work better). :-)
As the prop isn't attached yet, maybe you could run a wash over the engine as well, to show off that detail...
All the best
Rowan
