Reaper420, So I'm just reading your post for the 1st time and I understand your request for feedback - I love it and feel the same way, it makes me a better modeler. Sometimes it can be pretty quiet on here from what I've experienced.
In terms of feedback it's somewhat hard to give for 2 reason, I can't open the pictures to make them larger and be able to see some detail as it goes to another site saying I have to log in to see them and the more general reason is that pre-shading is one of those things that everyone feels differently about. That said, for me, the preshading would be too dark, i.e. I would put another top coat on it. Now I'm a guy who thinks real planes don't look like that too often so take my thoughts with a grain of salt. What I can say is that you don't want those preshading lines to be neat and tidy. I don't think making them straight as an arrow is the way to go. so I think what you did looks good. The ceramic inside the exhaust looks the part for sure. Agree with your comment on the ordnance too, the lines aren't always uniform.
So I think when alot of people read a post and don't comment, it's that they think it's looking good and there isn't much more to offer. To me it looks like your build is going great and it's gonna be a real eye pleaser when it's done. Hope this all helps and is taken in the best possible light
