Hey Elmas,
Here is a G.55 side view I did. I decided to show the prop in real view with dashed prop arc outline. From my point of view, the rivets don't intrude and add detail. I used gray ink and harilines for the rivets and rudder / aileron rib stitiching. I suppose I SHOULD have shown the rib stitch tape with the jagged lines created by pinking shears, but I chose the easy way ... slap me. If I had done that, I;d have to add the fabric edge tape, too. Possible, in a relatively short time.

Haven't added any background as yet and probably won't unless I actually use the drawing for something. Haven't yet started on the top / front views and probably won't unless the subject comes up again and is interesting enough to warrant the time and effort. That would mean that maybe I get something from the effort.
This one just for fun. I love the lines of the G.55, MC.202 / 205, and the Re.2005. But after you do a certain number of them the fun wears thin.
