Interesting. The orange and gray kind of trip me out...I'm not sure how I feel about it. He kind of looks like Carl the Safety Clone. "Remember younglings, look both ways before crossing the street!"
In all seriousness though, the paint job on this is well done, especially considering it's your first. I'd hit it with a little dull cote to tone down the glossiness, and add just a hint of weathering and battle damage.
I think the design pattern works well too, but I'm still not sure how I feel about the color choices. Still well done, and welcome!
