Fun experiment that, good job.

What you made, essentially, is a Bay Rum, exept you omitted the Bay leaves. Bay leaves has a spicy herbal sort of odor, and it lasts for a long time. If you try adding a bit of that into the mix, it should improve both the longevity and the complexity of the fragrance. The Bay leaves you want are from the West Indian bay tree, Pimenta racemosa, not the ones commonly used in cooking. Also, essential oils from woods will further increase the longevity, for instance, cedarwood, sandalwood or vetiver would all be fine in there.
