Thanks for the feedback. The form is curved from the bottom to the collar so maybe it is just the photo angle, I'll look again at it and see if I can see what you see. The blue parts are meant to represent rivulets as stated so you aren't wrong there. As far as having an off day, I could easily post a load of pieces that didn't work out. They all go to one side in case I get an idea to use or improve them.
