Problems to beggin

Since I decided I needed to do another movement, I have been trying to start a few times my second movement, however, every time I tried I am not feeling that I am really composing the truly second movement, so I deleted what I just did.

In a first stage of my compositional attempt I wanted to create another perspective of the material I sketched, giving to the second movement a sort of other reality from the first movement. In other words, changing the first character of the first movement (strings to the guitar). However, trying to figure out this idea have not been that simple.

I am having some problems composing this second movement. So, I started composing with new materials, even though I know that I need to use same materials I used in the first movement. Also, and the biggest problem is that, I feel that I am composing not for the musicians but for the machine - and that my friends is very dangerous. I am not enjoying nothing of what I am composing and I am afraid that that is because, at this moment, I am composing for the MIDI and that is blocking my creativity.
