I like the devil picture.
For the CatManDooDoo ingame it might need some work 
If I may be free to give some basic directions.
Your matrix in qubicle need to be in the exact same spot as the goblin is. The place does matter.
Also make sure you export z-axis: right handed. This is the standard that Radiant uses.
If you need some more, feel free to ask. Otherwise I can only applaud you for just jumping head first
