Thanks gents for the postive feedback! Really helps to keep the motivation (it was super hard to stay focused during all that lozenge application)
Regarding the silvered decals, I actually had tried fixing it via pin-pricks and future application prior to posting the pics here but it did not seem to help much and now the decals are pretty much fused to the lozenge now

The silvering in the pics is not noticable but I intentionally shot them at an angle where it wasnt apparent - it is really noticeable at higher angles....
Debating if I should try to remove that area of lozenge where the serial # is or just apply another piece of lozenge right over the top - seems both could screw it up further....
Dave - regarding the raised "C" on the wing center section - I think that is to just lock the wing into the fuselage maybe? There is a corresponding hole on the fuse where it slots together?
