First of all, this is an wonderful creation! The way the artists used the colours and the brush strokes - it give this painting a different level of mastery! The choice of the colours are very wise and expressive and the total work is done like traditional oil painting. Those brush strokes are normally achieved by palette knife on canvas, if I'm not wrong. But having that same technique and effect digitally ofcourse gains some extra points. This is not a regular digital painting, the artists has his own unique original style, and the style is very rare, totally noticeable among hundreds. next comes the lighting and shadows - the painting has fiery lighting mood. and it suits it very well. lastly, the painting style and the colours, and lights altogether gives it a really dreamlike fantasy effect where something can be understood and somethings are hiding beyond imagination.
Let me say first of all this is an excellent piece of art. The way you have created it makes it look like it has been done with paint on a canvas, not digitally.
The thing that stands out most for me is the way that nothing takes any definitive form - for example, the dragon - none of the features that a dragon has has being made to stand out, yet you can see it is a dragon. That is what makes it all the more amazing for me.
I think you have a very unique style and the colours you have used are brilliant. The background is simple and fits with the whole dynamic of the picture.
There is nothing here that I can mention you should improve on, or can add too. I love it all.
