Something which I find an interesting question, is the different 'styles' of profile art which I have often seen, even published. For instance, aside from the more detailed and weathered profiles like I've tried my hand at, often all that will be included in a publication is a plain line drawing which seems to serve only as a camo/scheme/marking reference.
So with this in mind, it's why I do not often speak immediately about such detailing when I see a new profile posted. Are these types of profiles a particular subset which the artist is working in? I'm not really well versed in the details of this hobby (as you all may know, I am little more than a beginner at profiling), and never have taken a look at the business side of the hobby.
