Lyricless compositions

Here's a track I have composed, and am looking for a collaborator on, just for fun, to see what it'd sound like. I was unhappy with my own Lyrics and vocal melody. What do you guys have?

We Gave Up (No Vocals)

Track 2 from my new collaborative project, tracks done, I just need someone to write and sing a vocal line on the top. 

Plot Points (no Vox)

The 3rd of 4 compositions seeking lyrics and top line melodies. part of my 'Limitation' work. the guitar track was written only allowing myself to use the D shape on the top 3 strings.
