A walk in the park, literally, and request for photography advice : )

It's spring here in the South West of England and the shutter trigger bug has come out of hibernation. I went to the local park and captured these shots during an hour's stroll. I used a Panasonic GH3 with its kit lens 14-42mm.

I'd love to hear what are people's favourites (I've numbered/named them for easier reference), some feedback on the shots below and any tips on how to improve my photography skills. Thank you : )
