Plot isnt a problem. I get so wrapped up in plot that i get lost sometimes. Dialogue can sometimes be a problem. Active vs passive voice can be a problem - i tell instead of show sometimes. But i love twists, i easily create original sympathetic characters (that i then kill off horribly) and I dont think i have any trouble with people relating to them or them being caricatures...

you'd have to ask alocin42 though really, she's my usual beta and she can tell you what i get right and what i dont!
