I like this!
In the end I had to redo the unwrap on the front window portion, because I had messed it up so badly! I had also made a few other mistakes on the unwrap. This ended up costing me a lot of lost time.
In terms of this image, please note that due to way that I work, it is very simple for me to change a number of texture elements.
For example I can change the depth of the panel lines, their darkness, or the highlights of their edges. I can change the opacity of the dirt layer that surrounds the panel lines, or the depth or dirtiness of the rivets. I can easily change the individual grey levels of the camo, including adding colour, and it is very easy to change from camo to a solid colour C130.
The only thing that would be difficult to change on the texture would be to have a completely different camo style (that would require a new camo layout).
In other words I can easily tweak this down the line. Indeed I might try a quick alternative style soon.
Looks great ingame!
Only got one minor suggestion: The wings look kinda bland - some decals (Nod logo or whatever) would make them more interesting.
