Step one of a new piece

Yesterday I sketched in the arches on some watercolor paper.   Today  I went back over it with heavier pencil and then a light coat of gesso scraped over it.      I'm still puzzling about what direction to go  next.    Collage, paint?   More drawing?     Time will tell.    

I've used these arches or similar ones in a previous work and just like the lofty feeling.
