This is a very nicely done piece of artwork. I know it must have taken a while, and I don't really have many criticisms for you! Good work!
The intricate design was honestly the best, and my favorite part of the piece. The dragon is done very well, especially in the midsection and head areas. The scales have a very good feel of indestructible power to them due to the way that you have drawn them, which is very good as well.
The only real complaint that I can think to make about the piece was that you could have brightened the colors up a tad bit in the background to help further define the shape of the dragon in the foreground, and possibly added colors to the dragon himself. While there is nothing to draw the eye away from the dragon, it would be nice to see him colored up.
I also love the Samurai Jack feeling that this picture gives off. I don't know if it is just me alone that can sense this, but it has a very similar design to the characters and creatures off of that show. I would say you have done very well with this piece, and I hope to see more from you in the future. Happy Drawing!
