Thank you for the kind remarks Vudak. Here's another update that took me awhile to get right. This is the right wings radiator inlet. Previously the inlet louvers covered the front area of the radiator housing. After looking at some photos there should be some brace areas on the left and right of the housing. Basically about 3 inches thick then it goes back towards the radiator.
I still have to make the louvers look as if they are inset within the radiator inlet housing itself. I also have to make the front side of the housing and door look like they have some kind of curves to them. The door may not be to hard but the housing just to the left/right and to the front of the door will be a pain. That area actually curves off towards the front of the wing. All of those shading details will be done later on.
I'm still tweaking every last line. Making sure they can't go any farther left, right, up or down without smearing onto another object. I know on the sides of the inlet housing that the panel line was at an angle but the is the best I can do. If I tried to make it look angled back it would smear and each pixel would cover the whole side of the housing from where the line started till where it ended.
Back to work for me.
