heh I can relate. I had a few years of art school at a place called Ringling School of Art and design. (illustration and graphic design, I didnt have a good enough portfolio for them to let me into the 3d program like I wanted them to. I was just outa highschool and to stupid to know better that they judge your placement completely by your portfolio)then went and got all my commercial single and multiengine instrument ratings at the flight school at Sarasota Airport next door. sunk 10 grand into getting enough multiengine hours in orlando for a FO slot instead of finishing my art degree as I hated graphic design and they wouldnt let me in the 3d program in an attempt to avoid being a CFI but got screwed and they took the money and ran along with about 100 other peeoples money. if you ever run into the williams family in aviation ask them about their little bastard child school called Airline Training Academy and watch them run away. ended up working at the airport line for a few yrs before needing better salary after getting married drove me into my family's roofing business

the moral of the story is trying to take the quick way will have unintended and possibly undesirable results.
the bright side is doing artwork for Aces High is a much needed creative outlet that I think my rather unusual combination of experiences is actually beneficial in this obscure art of skin making. the formal art training as actually more beneficial than I would have suspected. I consider myself a hack in this area though as I could never make a living off it. I am a commercial rated pilot and though I havent flown in many yers the experience of flying and knowing how airplanes are made makes my understanding of them and what they should look like more accurate. I worked the line for a few years and stared at airplanes all day long while I fueled and serviced them. I would stare at them and try to observe every shade and shadow that the aluminum skin would cast. I found that in many instances faint traces of the structure underneath could be observed. I developed techniques in an attempt to recreate this effect in the more recent skins I have made. This fact was reinforced by my roofing experience in which I did a lot of extensive sheet metal work with aluminum. I found that the slightest pressure to the aluminum will result in a noticable depression in the metal even in more heavy guage thicknesses.
but given this history my skin work is driven by an inferiority complex from past failures in that I couldnt make the cut way back in the begining when it counted. had I known then I would have drawn better or worked harder at it.
because of this any skin I make will never be good enough for my own personal tastes until I can procedurally make it look like the real thing. I am still well short of that quest but I find striving for this is beneficial in the drive for higher quality and better detail. which I find enjoyable as I like challenges even when I screw them up and fail at them.
but back to the skins..
everything on the skin needs to be drawn wehre you see it on the bitmap. its not hard once you get the hang of it just takes a little practice.
