You're most welcome! I agree, yes you should get them out of your head and onto paper. The beauty of fiction is that if it is a good enough idea, it continues to stew and become even better in there :) The flip side is that there seems to be so much more of ourselves that become vulnerable when writing fiction compared to prose; I think that's why critique can be so difficult!
You've got my support if you ever decide to "get more out of your head" :)
