Nice work! Those "nostrils" in the cowl really set it off, and make me realize that I need to hog mine out a little more. The opening flaps are pure genius
I'm really hit-and-miss on the photos too. I use the macro setting on my camera (a Canon A20 PowerShot), but the focus seems to vary, no matter how careful I am. Well, a fuzzy photo is better than no photo at all.
Keep the PA-18 faith!
