After a look over your wardrobe I'll suggest the following. I won't suggest specific frags, but categories.
All of your scents are recent releases. How about some classic additions to your 'drobe? Your collection leans towards the lighter, contemporary style, but you do have a few Orientals and a Gourmand.
You're lacking a classic citrus. And how about a vetiver? You could go with another fougere, perhaps in the more traditional style.
While I emphasize older, more classic scents, you could just as easily go with more modern versions of citrus, vetiver, and fougere.
For heavier scents you could look towards those with lots of woody notes. If you're inclined, check out the '80s scents for strong, complex fragrances. If not, then perhaps one of the niche offerings might suit you better.
