The first composite did not turn out well. Mistakes were made. Long drawn-out fights with the render farm ensued. I did learn a lot from the experience.
Poblems with my layers
Some of the issues I encountered included forgetting to double check some of the overrides that I set within certain layers. I am new to rendering layers and shuffling AOVs. One valuable lesson that I learned is to stay extremely organized and carefully name everything. Above you can see where I forgot to tun off the sky dome in the reflection pass. Also I left on the cast shadows for onr of the ground passes causing red reflection in the dragon.
The renders above were from my final composited animation. YOu can clearly see many issues that I will be working out over the next couple of weeks.
