Hi Francesco
Your mix sounds great... because I love mixes with clear and different depths. It makes them more interesting and also transparent in my eyes. Nevertheless: Your example is probably a bit overdone. There seems to be a bit a too large gap between "close and far". But as always: This is a matter of taste as well.
...gaining better understanding of those IRs...
IRs are room prints of real rooms. So when they have very natural "implemented" distances in the recorded sample you can have those distances back together with dry sampled instruments. As Dietz mentioned above: Only the one who recorded the IR and gave them the names could tell us what "rear" really means from case to case.
Approach:
It counts the result. Try to use more your ears and less your eyes (text) for making decisions. Some IRs are not able to put an instrument very far away even if they have got the names "rear". Play an instrument 100% wet "through an IR" and the sound tells you immidiatly whether it sounds "rear (far) or not".
I personally searched VSL's IR-Library for all those IRs which really can make samples sounding "rear". Funny: There are some IRs of smaller rooms which can do this job in a much more better way than others of large rooms...
All the best
