Hello there, Inspire.
Thank you for your kind words.
I have bought many very expensive sound libraries during the last 2 years. Some from Garritan, some from ReFx, some from SoundsOnline. In these songs, I have used a little from all of them.
The best way to learn how to do this kind of music is to spend a lot of time getting to know your sound libraries and their weaknesses and strengths. For example, I take separate notes of all the great sounds in my sound banks, describing in detailed sentences how they sound and how they can be used. You also need to find your own sound, matching your own inspiration, and understand which sounds you need to create music in your style. There's no 1-single-super-sound-library that has it all. So try some different sound bank demos or cheaper light variants from different vendors and try to figure out your needs.
I am sure you will succeed if you just spend some time with it and don't rush it too much. When I rush my instrumentations & compositions, they end up in failures. So I try to not do that anymore.
Best Regards
