Okay,
I am really enjoying this. I think it is great !!! I have been looking at it for a long time, and have some more comments.
I mentioned the jacket in an earlier post. Now I realized what was catching my eye and did not feel right in my crazy mind. The hat needs to be "relaxed," on the sides and the folding over of the sides should be thinner. I love the detail of the piping and lower emblems they are perfect. One suggestion would be for the eagle emblem. You modeled the metal pin version, have you thought about doing it as the embroidered patch? Also can you add a little more sideways tilt of the hat towards the pilots right side. Hanz "assi" Hahn wore his hat at an angle as opposed to straight and level.
The ritterkreuz is hanging too low, the top of it should be halfway up the length of the shirt collar height. It looks like you have captured the shirt opening correctly. However, as it is now, it appears a little too open and informal for an officers shirt. But I think if you move the cross up it will work perfect. Also I think your edge loop in your model around the top of the collar is too far away from the top fold. Try pushing it up and inward to gain a more crisp edge. Is it a shadow in the rendering or is the neck folding over the collar on his left side?
One last thing would be to customize his left eye. In all of the pictures of him from the past. His left eye was a little more closed ( very flat compared to right eye). His lower eye lid (inferior tarsal plate) was pushed out more on his left eye. It is hard for me to see it in your renderings. I almost think that you should flatten the right side and pull out and up the left side as well as flatten and close it some more.
All of these that i mentioned would be my wish list. The artist always has the final say. Whatever you do keep going!!! It is really refreshing to see something new and different.
A question for you. What software are you using to model all of this?
Regards,
Todd
