Not to re-stir the hornet's nest, or resurrect a seemingly moot issue now, or start The First Flame World War, but I'd like to give my say on "copying:"
Chris' model is outstanding - "copied" or not. Why, we are ALL GUILTY of "copying" - down to the way we apply putty (say, following - correction - copying the alcohol method), or creating copies of ammo boxes, etc. with hot glue from a glue gun, or following the weathering advice in the "Weathering Heresies" feature on this site.
If following the same tried-and-proven-and-battle-tested technique is called "copying", then what's the purpose of asking "How do I dry brush" or reading the weathering, building, etc. techniques on different sites - this included? No one, IMO, has the RIGHT to say "Aw shucks, your model is good - very good indeed - but you merely copied this-and-that's technique so it's piss-poor really, so sorry." I know I'm being harsh, and what I said was "extreme" but come on, give credit where it is due! Chris (and I don't know him) made that tank in excellent form following a reference. Don't all of us do that? Don't we make Track-Link, Missing Lynx, Armorama references? If using a reference is "copying", then WE are ALL COPIERS.
It's different to use weathering or lots of stowage to hide build or paint defects (of which I'm guilty of), but when the overall finish is excellent, no need to lambast a good build. Saying "It's just a copy" is no different to being a "reviled" rivet-counter or kit-knocker, at least to me. And here I thought everyone in this site was above that?
BTW, I'm "deeply concerned" by the way some people label their techniques as "their own" or at the very least fail to give the source of the technique, when the same could be read in, say, some FineScale issue or a hobby book. I've noticed this occur (I won't name names though) and to me, THAT is copying.
Sorry. Rant over. It's just the same as telling a neophyte who did an excellent first job "Sorry, just a copy. NEXT!" even if it's an excellent job. Give everyone a break.
BTW, I'm not targetting any particular person or persons on this thread. I'm just voicing my opinion.
Sigh... we should all learn to enjoy the hobby, rather than get mired in the details.
