Hey thanks for fanning and commenting :D i've read your stories and i'm not really good with giving advice about writing, but I do like your ideas! So the only thing I can give is this: What I do before writing each chapter is that I brainstorm what's going to happen in it, so it's much more easier for me to write that chapter and this will make your chapter a bit longer. And that's really the only advice I can give so hopefully this will help you :) And the thing about writing is heaps of practise I think that's only thing you need!
