Introducing Madness

So.. it's the first time I write a critique...

Here's the positive points:

First of all, the colours are great, you made something very nice looking with coloured pencil. The outlines are very smooth too.
The design of the night fury is original, yeah... And this came out very good.
The "texture" you made with these pencils on the skin of the dragons give a very nice effect.

The expressions of the characters are well done too.

Now the "negative" points :

There isn't shading, so we don't have any idea about were the light come from
And the background could have been more linked to "Madness", you know what I mean? I think the green don't fit enough with that.

Here it is. Otherwise, this is very well done! Continue like this, this work is great!
