The Red Dragon

STUNNING. The first thing that caught my eye when I looked at this piece was his neck. The pebbly style there is beautiful, and the internal shading makes each stone stand out individually.

Your colors are perfect, each one balancing out another. His eye stand out over the red and gold, but to make it pop even more, you might consider adding some small scaling around it, and some highlights on his brow.

His face, properly majestic and terrifying, could do with some more shading. Perhaps, using the eyedrop tool, you could take some of that terrific color from the spaces between his neck-scales and make his face shadows deeper and darker. Especially under his horned cheekbones.

Also, it may be a good idea to go over the lines on his head once more with an opaque red brush, to make them a little bit darker.

Other than that, I have not much more to say. You are clearly talented! I look forward to seeing more of your art.

Hope this helps!
