Just the man I hoped would chime in.
Yes, I am doing early Serie III for this skinpack. You are correct about the GAC. I had yet to blend them in as historically correct but look below in my pics and tell me do I need to soften them up more.
Also please be critical of anything. I'm more concerned with my colors than anything currently. Do these look correct or need adjusting?
Here are the first three skins. Please be critical of anything needing adjusting; colors, weathering, panel lines, etc...
