First I must commend you guys for a beautiful new Dora model! WTG! However I did spot two problems:
1. The leading edge of the wing has a very sharp polygonal angle that makes it invisible from the cockpit and makes the wing look like a flat plank of wood. Adding a couple of polygons or rearranging the ones used elsewhere on the wing would make the wing look correct from the cockpit (which is the most important view after all).
2. The propeller shape is wrong. The one used now looks like the 109G-10 prop, not the huge wooden paddle-blade prop used on the real Dora.
Apart from these two issues I was really impressed by the new model. Wonderful work!
