There are depictions of dragons with two legs, and even no legs at all! Look at some images of "lindworms" and "wyverns". Anyway, who's to say what a dragon should look like? A dragon is a mythological creature, so one should be free to take their imagination as far as they like when designing one... I mean, I've seen dragons with multiple heads and more than two wings. With such a long history and cultural range, it's not surprising that dragons are so wonderfully diverse! : ]
This is lovely. The droopy claws on the feet, the sinewy tail and neck that almost seem floppy (and that balance each other well), and the insect-like wings are all so charming.
If I were to offer criticism, it would be that the background is a bit distracting. The dragon and gold heap are so detailed and engaging themselves, and flow so well, that having a textured background, or one with a border even, just pulls the eye away or breaks the line. At the same time I realize that clearing the page of all the pencil marks or photoshopping just the dragon onto a blank background could be a major pain.
Also, your color choice for the dragon and the way you did Smaug's details really makes me think of a hard, armored carapace. Which is fantastic.
Jéééé Šmak, toho mam ráda asi hlavně kvuli tý obálce kde je x"D Ale ten tvůj vypadá strašně hezky...je úžasně obtloustlý a má super hlavu c: chci ho domů. (k té další tuně věcí co chci, mezi jinými je to i ochočené tornádo)
I very much like the "free" quality of your linework and the rustic yet regal color palette. Fitting!
My one small critique is that there is some visual awkwardness about the golden branch (cloud?), on which Smaug is perched, in the corner where the outline breaks the image border. Your drawing interrupts the border in 4 other places, but they are all parts of the dragon and are situated in a balanced way along each edge. The color also continues despite the border. But in the lower right, the branch does not follow this pattern. A simple remedy would be to erase those black on the border, or maybe redraw the branch's bottom a little more to the left.
thanks ah that thing XD .....eh...true's...i was so lazy(and my combuter too!...it's taking him years to make one simply thing on picture ) and i thought nobody'll notice it...hm....maybe i'll edit it latter
