The more wind you have, the blurrier the results will be.
Shoot with some light in the sky for more pleasing results.
In addition to the above, use exposure compensation to bracket your exposures. I would use full stops, like +1, etc. my guess is that nailing the correct exposure is the biggest issue after image sharpness.
