first i want to excuse my bad english, i hope youre understanding me

Im now producing Dark, Experimental Psy since an half year and there are still many questions about sound design, eq, fx and drums
1. I want to make sound like Kaikkialla here an example of his new projekt with holly manullu:

2. I want to know how he is making this organic Atmosphere sound
3. How to arrange my drums and how to eq
4. How to pan sounds(atmos) that they dont interrupt my bassline
5.how to arrange my cutoff on the leads that they become not to fast but still rythmic and how to cut them.
