Got back to the script, and changed... some of it.
Actually, not as much as I thought; I'm pretty happy with the progress I've made - and any more tinkering could be overegging the pudding. And the point of having work critiqued by the rest of the group is to help you concentrate on the big stuff that you've not seen for whatever reason.
So I could do more (you can always do more) but I won't. I've uploaded it to the members page of our website, www.derbyshirescriptwriters.com, and I'll try not to think about adding another Zeppelin chase sequence until my crit session next Tuesday - Andy.
