(So, this is my first critique. I will try my best to offer fair and constructive critcism, and will be rating this on an novice-intermediate artist scale.)
First of all, I would like to state that you have made leaps and bounds of improvement, and this picture is solid evidence of that. While it is not revolutionary or groundbreaking, artistically, this image is the product of a very unique technique that you have developed.
The exclusion of scales on the faces of the dragons allow for smoothness and clarity, while inclusion along the neck adds a touch of realism and detail. By the random formations of the scales, I am assuming you have drawn each by hand? If so, then I believe this technique can be quite time-consuming, yet it is well worth the effort - it is very unique, and gives a high degree of detail without overdoing it. Because of the unique nature of the technique, you have scored fairly high in the originality and technique factors.
When I first viewed the picture, I was impressed - as I mentioned before, you have improved, and your technique is a very good one, but I was not blown away. Perhaps adding more detailed lighting effects, a background or more advanced shading would have contributed more to the "wow!" factor. Still, when one looks at this picture, one can really sense the emotion and love in it, and you did an amazing job with conveying that. Because of that, you achieved an above-average score in the vision and impact categories, which is fairly good, but there is some small room for improvement.
Overall, this is a very nice sketch - the emotion is vibrant, the technique is unique, and it is quite original, yet perhaps, next time, more can be added. Very good work! Keep it up, Star! I look forward to seeing more from you.
Nice work, I really like the pose and the way the colors are similar, yet slightly different!
I do think smoothing the lineart would really help, as TehAngelsCry mentioned, but overall this is a really nice piece! The shading is very lifelike and the shadows behind their heads really add some depth.
