Right steph here we go,
I think you have 3 parts here, hammer on part, chord part and unconventional chord shape part - hope that makes sense
I don't think as an instrumental this works , particularly at the end shifting from unconventional chord part back to hammer on part.
I do however feel that the 3 different parts in isolation are very interesting indeed
My advice would be to adapt the structure to fit a melody and lyric in
Even better there are potentially 2-3 songs here which could be developed here - I do this a lot
Work with the hammer on part into chord part first and see what happens and potentially use unconventional into chorus/mid 8
Hope this bloddy makes sense - i know what I mean
I really like your guitar playing and still love family man
