Newbie perfumer

Hi guys! im a newbie in perfumery but actually done some basic mixing, i have a basic formula here
what i want to ask you guys is how i can make my perfume strong? i dont know what term to use.. just an example
like filling out an elevator with your scent when you enter... sorry i cant really imagine a word for this hahaha
heres my formula:

Fragrance OIL 25%
DPG 3%
Fixative(civet) 0.6%
Alcohol 97 (perfume grade) whole mixture until it becomes 100ml

what do i need to adjust here for the diffusion rate... it smells good and last long but evaporates very slow, what i want to achieve is to maximize the projection and sillage if im using the words correctly

Iso-E Super and ambroxan are two aroma chemicals commonly used in modern fragrances.

Iso-E dramatically increases projection, and ambroxan has taken the place of ambergris to aid blending and extend longevity. 

Each adds something of its own to the scent profile as well.

Yes, Iso E Super and Ambroxan. Also, amberwood aromachemical. Hedione, if you want to add floral notes. Naturals like benzoin, labdanum, frankincense can enhance projection/sillage, too.
