I've done this before (I'm practically a professional editor!). The next step is actually giving a copy of your manuscript to someone else you trust and have them read it to give you feedback (and I'm more than willing AFTER I finish Liz's novel first!). You need another set of eyes to pick up on the stuff you can't see and to find the plot holes. (PICK ME! PICK ME!) ;) I can walk you through this. After next week, my life will calm down like WHOA because my classes will be DONE!
