@Donovan Brady your formula is not short on any long lasting materials, but those are not all "fixatives" in the traditional sense, like benzyl benzoate or benzyl salicylate are. Other materials you have listed can be perceived as fixatives but they are just longer lasting with their evaportaion profiles. What carrier are you using? Did you let it sit? Just taking a look at it quickly on paper, I'd think there would be a projection issue as everything is heavy. When it is too heavy, it can be muted/flat, To answer your question directly about identifying, it is a process of elimination. I'd either remove one at a time or halve one at a time and see if there is any change.
