Well, I think I'd know what to cut in the same way you think I should know what to add! Seriously though - I wouldn't be worried if I were only 5000 words away. It's being 45,000 words away that worries me.
I overwrite. I just can't help it. Then I thin it all out after I spend some time away from it. I tried writing bare bones... it doesn't really work for me.
I'm over-descriptive. I don't get flowery or complicated about it, I just put in waaaaaaaaaaay too much. Was able to keep descriptions at a minimum in my book, but only insofar as I avoided unnecessary world-building. So yeah, I tend to run off at the mouth.
Over descriptive on my end. I have a strange tendency to believe that anyone I ask to read for me has a brain of fried tripe so generally I have the urge to keep explaining things
I can't stand over descriptive writing. That kind of writing was okay fifty or a hundred years ago when people wanted a picture painted in their head. Now a days there are pictures everywhere and we know what everything looks like thanks to the internet. I try to put only what the reader needs to get a picture in their head, and I only describe whats important. I let their imagination do the rest.
over-describing or too much of anything is never a good thing... nor is giving the reader too little information... so i do neither, though i probably tend more toward the 'lean and clean' side while not stinting on imagery that will draw the readers into the scene without boring them by micromanaging [what i call BIBO writing, as in 'breathe-in/breathe-out]...
