Which style

Hello all, finally worked out how to get the little pictures. I now am not sure which to put as my style haha. We're having a registry office ceremony, which is inside a castle. Our reception will be on my parent's land and include an overhang off of a farm building, as well as a sailcloth marquee. We're thinking colourful wild flowers. We'll have fish and chips, outside games and a couple of live bands. What do you think? We think festival but that's not an option. Rustic? Countryside?... What's the difference? Thanks.
