Looks like there are plenty of ideas for GdT to pull from, then. Thanks. 
Right you are, per Google Images. I also found this Howe painting of Smaug at his leisure: http://www.john-howe.com/portfolio/gallery/data/media/1/Smaug.jpg
And Ancalagon: http://ring-lord.tripod.com/Howe/ancalagon_ship.jpg
And a wingless Glaurung (looking a lot like a gila monster): http://ring-lord.tripod.com/Howe/glaurung.jpg
Here’s Rankin-Bass’s (silly, IMHO) take on Smaug:

Then there’s always the Welsh flag:

The two Tripod links are broken as is Smaug in Lair.
The very bad Rankin-Bass smaug should have been broken.

Heh. Elendil’s Heir, some of your links dont work for me. Is this “pay pack”?
For example, your 2nd Rankin-Bass link says “Access forbidden”. Registry required? (The first link worked. The guy made the dragon with feline seeming features.)
Hmmmm. :dubious: They all worked for me on Preview. I can’t explain it. Try Google Images for “John Howe Smaug” and “Rankin-Bass Smaug,” and you should find 'em.
