Ok, guys, thank you all for such a positive and inspiring feedbacks.
@Marc O'Callaghan Thank you for pointing out correct names for the strings techniques markings and overall detailed feedback. It was tremolo at first, but I found out that legato is much more suitable. Unfortunately, I forgot to make changes in the score. About the mess with violins at m.25 - I actually thought that it would be hard for violin players to jump from that upper G down to that C on a G string, so I gave that part to 2nd Violins. But I might be just overcomplicating things and such a jump isn't that hard. Creating humorous track was exactly what I was planning when I was creating D 60 - I'm glad that I've managed to do it so you and @Ken320 actually noticed that. And yep, you are right about Hans Zimmer - his tracks inspired me for creating D 55.
@Maarten Bauer Thanks for the advice, I will definitely do this. I'm also thinking of taking online courses in Berklee Universty.
@LostSamurai I honestly never though that someone will react to my pieces in such a positive way. Thank you for inspiring me for doing more.
@Adrian Quince Thank you for advising me a list of composers to listen. I'm listening to their pieces while writing this))).
I'm glad you all enjoyed my compositions.
