Be aware that the 1:25k's are 50 years out of date. Even Yahoo! is 5
years(?) old. It's surprising how quickly hedgerows disappear, or in
recent times, appear.
Also I think you've missed a couple where they disappear under the
labeling on the 1:25k.

It's certainly a good start. Naming of streams, if they have one,
Adding/naming farmyards, woods etc would advance it along nicely.
I notice you tagged some areas as forest when they're labeled as woods
on the 1:25k.
I also think that labeling any wood in the UK as natural is incorrect,
but I'll put that forward for discussion in a separate thread...
