This is model I created based on the character ‘Orthos’ from Will Wight's ‘Cradle Series’.  There are two versions uploaded here, one in a neutral pose , another in an action pose and the third file is the dragon's breath which in the image of the printed model is attached to the action pose. 

The one in the photos was printed in transparent red PLA and painted. It has some negative bodies in the interior where I added white LEDs.

The models are FAR from perfect, please feel free to mod and improve them if you like.
