I listened to Parsecs No.1.
What I heard is, more or less, a rigid succession of mono-textured panels.
There are many issues, I think. First, you should work on making more interesting transitions. This process will include a more elaborate transformation of the original textures, i.e., not just the mere presentation of the texture.
Second, polyphony, i.e., more than one sound at a time. This also will make the textures more interesting and not simple and monochromatic as the ones in the piece. The elaboration of this polyphony also will help to make the transitions and the general shape of the piece.
So, in general, use all the resources we have from western music in combination with the new possibilities offered by this new electronic medium.
