You obviously have a lot of talent and had great training. All of the major a technical concepts are well drilled and confident. If I could only add maybe a couple of small ideas that could help.
I have played against 3 star girls and ex - highly ranked D 1 players (Yale etc. in their mid...
even though these aren't Fedal finals, but I was at the Ryan Harrison/Stahovsky match at the US Open. Amazing energy. Also I was at the Oudin/Petrova match last year at the Open...amazing energy from the crowd!
You can also go down the line during the rally too....you don't have to do it on the serve esp if the person has a good serve. hit a deep crosscourt shot return and if you see a ball that you can change directions on, rip it down the line!

(all USTA leagues)

2011: 5.0? (fingers crossed, really hard transition!)
It is hard to make a real opinion without real gameplay videos. Sometimes pretty strokes and shots go AWOL in a match....if this is how you play in a match, 4.5, if you compete at 75% of the level of the video, a strong 4.0.
