Here is an image I am working on 

It is my take on the Manticore.
I would like to make it look as awesome as possible, yet I am uncertain on how to proceed?
It would be cool if I could tell some sort of story with this image, some narrative elements perhaps...maybe I could adorn the Manticore somehow or make it look more like some sort of stone or marble even. Then I could do engravings or something.
Any feedback and or ideas will be most helpful
The software I am using is Krita.
Here is an update:

I'm going for a metal type look... 
Another update 

Update 
This is a quick update, I decided to go for a burning city in the foreground. Like Troy or an ancient city aflame. Now to refine and complete the image
