Nice work Orionfield, however, I believe there is a better Twin Otter drawing in the archive that you could use. Check under FD Scale - Real Designs - Air - Vietnam for the base drawing. Cheers!
Yeah, the one I used is on the older side, but it wasn't worth the effort of converting a -400 model to a -300 model to use the one you suggested. I added more shading and made some small tweaks to the template before I did the Air Guyane livery too.
While working on my next project, I found that the CRJ-100/200 was missing its forward emergency exit door, so I updated the template and fixed the panel lines to be more accurate. I removed the baggage door (since thats on the port side) and added the APU exhaust.
