Hello world, and in advance, sorry for my bad English

I'm working actively on music from 2014 and created over 100 tracks, but still struggling with proper sound processing and design (which is really a headache). I've read many tutorials and books but they seem not very helpful in practice, in every individual situation. So, the main problem is understanding: I listening the other composers (I don't even saying about professionals), feel the space and dynamics, see transparency, but can't understand how exactly they do that, and can't even replicate the effects (well, I can do some now, but it taken ages to get it). 

So, advices about sound processing (especialy about working with sounds of virtual orchestra), would be highly appreciated. And also, about mixing and mastering process. If you know the video tutorials (because of practice examples) focusing on working with orchestra sound and other cinematic effects, I will also be grateful.

Here the three examples of my overall progress:

Thanks for your attention.
