Looking at the first set of photos you posted.....I'd swear that was a much larger kit. And then you go and post the next set with your knife as the "point of reference" .......and I'm completely blown away!
I am doing vents at 1/350 scale, which is trying my patience.....and yours are half the size. Good Lord, you must have a steady hand and a HUGE magnifying glass. I don't think I've seen this scale kit done so perfectly.
Well done. I, and everyone else, look forward to more progress photos.
