Firstly, thank you for your review. I don't say, you're wrong, but I really didn't want to use bigger dynamic contrast in this case. In other cases, for example, in the music piece I linked, I faced many technical issues. It's hard to adjust the dynamic level of all the instruments properly. My purpose was a quieter sound at the beginning of the piece, but the bassoon and the violas together were too loud. But, if I turn the volume down, they can't be heard, so I left it louder than I wanted to. The final mixing was quieter, but the mastering always decrease the dynamic difference/contrast, so I have to say, I'm not a mixing engineer, and for me, it's a serious difficulty to create a clean mixing, highlight the main instruments, and adjust the proper dynamic level. So maybe I wanted more dynamic contrast, but it's hard to handle the volume in the case of symphonic music because there are so many tracks and instruments, and some instruments almost have the same frequency range/upper partials, etc...
Thanks again, and have a nice day! 🙂 I always appreciate your comments!
(Just to clarify, it wasn't me who reacted with the laughing face on your comment, just so there's no confusion. 😄)
