This all started from a Dungeon and Dragons campaign I got to be part of.
Nothing is more Dungeons and Dragons than a dragon, its even in the name!

While the DM ( Dungeon Master ) was describing the dragon, how it started to burn the whole city and everyone was fighting to stay alive. I opened the Ipad and started to sketch a fast doodle just to get my imagination started on paper. (Yea great team mate to play with)

After the game, once I got home, I started to sculpt a very basic form of a dragon. I wanted to see if I can place it in my image to paint over. In photoshop.

I open the rough doodle in photoshop, render my sculpt out of Zbrush and place that in the shot. Something was missing.

In Maya I open one of my basic human base mesh's and take it to Mixamo to auto rig it and pose it so I can have a human form in my shot other than stick figures with shadows.
Once I had everything in photoshop the fun begun. I started the paint over with photobashing to dress everything and the final result is what you see.
If anyone wants to see a full process of something like this let me know in the comments as I can record on the next one step by step and show how to blend 3d and 2d together.

I hope you enjoy!
