I would say that you have a pretty good foundation to begin building upon, knowledge wise. You are correct, in a general sense there are fragrances that are more season appropriate than others. Your listed fragrances all fall under the “designer” category, you may also want to look into some “niche” fragrances (they tend to be much more expensive, so, designer is a great place to start). Summer and spring are lighter fragrances, and, the aquatic, citrus, green realms are somewhat the standard. Winter and fall you see more gourmand, oriental and spice. Warm weather fragrances usually have less projection, are less dense, and are more transparent versus the thick, heavy, strong cold weather fragrances. You have clearly done some homework (and hopefully have tested the fragrances listed as well as researched them.) I would say that you are headed in the correct direction. Let me throw the following suggestions in to the mix;
You may also want to do yourself a favor and test out Millesime Imperial and Rose 31. I know at 17 I wouldn’t have been able to afford bottles of these two fragrances, but, they are both fantastic scents that get a lot of attention. MI is a perfect warm weather fragrance and Rose 31 would do great in cold (though, it is very good in warm as well). Figure out what you like, read reviews and forums on this website, and test, test, test, test, test. Welcome! Enjoy the ride!
