I second what @pateceramics said regarding the video, especially as your piece and the one in the video don’t have that much in common besides the composition of the ensemble. You use the contrast of thinning and thickening the texture extensively, and this often to great effect. At first, I wanted to criticise some of the harmonies, but soon I realised they are part of the style you employed. So, fine with me. The only tip I can give you: You deal with some of your ideas rather quickly, like the passage in 6/8, or the slower passage in m. 68ff. Also, the “timeless“ part could use a bit more timelessness to convey its meaning … . Probably you can develop some of these phrases a bit more along the lines already mentioned if you want to lengthen your piece. However, I would advise you to not overdo it. At the moment, your composition is certainly not boring, and you should keep it that way. (The main motif is especially energetic!)
