The attention to detail (and the smallest details) is what makes Heatblur products so attractive IMO. So naturally, they attract like-minded individuals. It's not surprising to me at all. While leaving out certain details to incoroporate a generic global feel might seem like a no brainer to some, to the ones who are detail oriented, it's like an "unflyable" situation. LOL. They know something is missing and they want to make it as authentic as they can.
As someone who makes liveries and does so with much research and collaboration with others to get the most information about a livery - I try to make something as authentic as I can. Which means for me, I'd rather not associate my name with anything other than what I feel is my best effort. So, my guess is that is how the other "rivet counters" feel as well. It's a "take pride in our work" thing. Not a "we want to be difficult" thing.
