No problem mate
I plan on doing more of these how-to's/tutorials, I just need to find the time to sit myself down and paint/make stuff.
Keep in mind that the Humvee is only about 70% finished, there is still a lot of work to do! (which I will take pictures off).
I noticed that the lighter brown in the pictures appear way to warm, its not like that in real life. I'll try to get a few photos of it outside today in natural daylight to show you what I mean. (and if that doesn't work I'll do a 50/50 mix of the dark brown with the light brown and paint over it, only leaving the lightest brown at the further most edges (highlighting).
