Nice! I always enjoy viewing your latest work. There's not much to critique here- it's a cool design with a stormy background and fire- what's not to like?

A couple of things; firstly, the hand reaching out towards the viewer perhaps doesn't pop as well as it could. It's the same tone/ colour/ saturation as the body behind it, though it's clearly meant to be closer to us. The part of the tail that curves away from us is very strongly laterally compressed, though the rest of the tail isn't all that compressed and is more cylindrical in shape. Also, maybe fading the more distant wings a bit here and there, in a similar manner to the tail, might help with adding depth? (Though the depth is already quite nicely established on the wings, and convincing too.) Finally, though the dragon is well-balanced with regards to shape, and the flowing anatomy looks appropriately sinuous, it looks a bit squashed/ restricted in the composition on the bottom and slightly at the left-hand side too (though this last point is really debatable, because I don't really get that squashed impression when viewing the small image, just the full-view. Perhaps mirroring the artwork in Photoshop could determine whether or not I'm being too super nit-picky).

All of the above points are pretty minor crits and probably overly nit-picky, and I don't know if they'll be helpful or just annoying! I'd like to say that I think the scale detail is lovely, the muscles are really well-shaded, and the colours are way cool. Black and red always go together! The markings on the wings are quite intriguing. The curving body and four wings just look plain cool. Also, the slightly spotty watecolourish texture on the top-right clouds helps to prevent them from looking too soft overall.
