A series of related musical pieces

These are each built around the same interval that begins the piece, with also some borrowing of melodic lines here and there.

Piece #1 surprises from the 1:00 mark, especially when it explodes at 1:40. It is quite somber. I like the arpeggio in the background and the 2:15 part which reminds me of Scriabin. Impressive.
The beginning of #2 is delightful with the pizzicatto, strings and cascading winds. And what a surprise to hear some castanets with the brass. Well constructed crescendo, in my opinion. As well as the denouement with that glockenspiel-like timbre perhaps.
In #3 there are new timbres like the harp and that descending motive, ... well, the orchestral ensemble is very nice.
#4 recovers certain rhythmic bases but it seems to have a somewhat oriental undertone.
The agitato of #5 flows nicely into other marimba or similar timbres. And then some powerful timpani. This reminds me a bit of Shostakovich.
The serious and elegiac tone of the beginning of #6 continues with a fantastic brass ensemble with rolls that seems Mahlerian to me but then there is another very impressionistic explosion of color. And a big end, like Strauss.

All in all I find it a wonderful orchestral suite.
Thank you for sharing and congratulations.
 

I really enjoyed your creative use of percussion!

Such a versatile section of the orchestra, and yet often underused.

You've managed to create an epic colourful sound, and I think percussion helps with that.

The third piece is my favourite. Love the melancholic opening passage, and the layering of the orchestra in the later section.

The renditions were rather good too: you obviously know how to produce and construct orchestral music.
