This is a nice academic orchestral music with good orchestration. I can hear the influence from almost two century of classical music from Verdi to Brahms and too many musical catchphrases from Beethoven. When a composer is writing today classical music (or the so called neo-classical) it is always difficult not to sound like something heard before and this ouverture is not escaping from that. The quality is there and the hard work shows but the originality ... well ... it is far from Saint-Saƫns - Symphony No. 3 in C Minor, Op. 78 for Organ.
The production is impressive considering the tools used. Indeed, it may be a question of real concert audio reference or taste but some virtual instruments are not as convincing as one would prefer. Indeed, repeating notes sounds like machine gun (due to the lack of Round Robins in the VST used) and long notes does not have the expressivity a real musician should provide on long notes such as a crescendo after the attack and then a slow decrescendo. A steady volume and expression doesn't sound natural and that can only be fixed using the dynamic controller if your VST allows for it. Indeed, around 10:30 what I believe are the horns and then the trombones plays long notes that are so painful that I was so happy to hear the woodwind even though they had that unnatural looping vibrato. Producing with virtual instrument is not easy I must admit. When you produce your recording composing is only 33% of the work. You then have to play the score for each musician with the necessary expressivity (another 33%). Indeed, your score is only notes. The instruments is altering it in order to make it sound better, which is not what I can hear here. Then you have to be the concert master that balances the instruments expressivity over and above what the composer believed was appropriate (another 33%). The remaining 1% is the sound recording that you leave to your virtual instrument VST and if it is a very good one should be easy.
Hope that will help.
