Hey. So, I'm wanting to make some Aviators (those retro shades cool kids wear), and I can't quite get the shape right, without making them too big. So I started off with this;




I know they're not perfectly round like they should be. They have a shine on the lenses, and are slightly transparent.

Perhaps someone could draw something that is based on my drawing? I won't use it as my final drawing, just as an aid. Criticism and feedback appreciated.  

Mine turned into goggles (kind of), but the shape should be appropriate. You can use the colors, shading, shape, or even the glasses themselves. I don't really care.  

I know this isn't the kind of help you were asking for, but...
Hither are my Great Grandfathers Aviators from back in the day:


And, looking at them, while I think you have the colours good, they're too round. In these ones, there's a straight edge at the top and outer side, and curved at the bottom.  

Thanks, both of you
