Experimental Walnut Stained Wild Rabbit Skull

Testing out your suggestions on how to improve my homema walnut stain! 
This batch I added 75% ethanol as a preservative. It interfered with the super glue and as it evaporated leaving a white haze. 
These are experimental as I work out what works best. 
Skull selected at random. You might not receive the exact skull pictured but all skulls are similar in size and from the same staining batch. 
Rabbit skulls are juvenile wild rabbits from local culls due to over-population.
