First - and I think most important - it is your quilt! Whatever you decide is the correct decision. Having said that, if you are not comfortable with your feathers and afraid you'l 'mess it up', this might not be the top to practice on. Do something a bit more simple and let the log blocks stand for themselves. Perhaps a spiral in a few of the logs of each block. It does not have to be an allover pattern unless you prefer the squashed down look. Or, depending on the layout, perhaps a diagonal running thru the whole top. I'm sure it will be lovely no matter what you decide.
