Both pieces are lovely pieces of music, well thought out and stuff, but......
They sound too bright to be real. That's always the problem I have with VSTis. When I listen to virtually all my usage of them from 2004 to last year, there's a brightness and reverb~y ambience that always slightly irritated me. Well, on some of them, like Miroslav Philharmonik, I worked out how to turn all the FX and ambience and brightness off. Makes a big difference. Record them dry and dull~ish and go through the hassle of doing one instrument at a time.
These pieces sound like the kind of sounds that keyboard wizards from 70s prog bands like Yes, Genesis and Kansas would use in lieu of actual orchestras.
But as actual pieces of music, I dig both yours and Dusenberg's.
