Request for Engraving Suggestions

[Alberto Simões]

Hello

At [1] you can find the images of the engraving process of one 
transcription I did. The Lilypond source file is available at [2] and if 
you prefer the PDF version, it is available at [3].

In this engraving I do not like the amount of space between the two 
systems. I understand that there is not much that Lilypond can do, but 
the overall aspect is kind of... strange.

I am writing to ask for any suggestion to make this output better.

Thank you
ambs
