Ah, I really miss the ocean and will plan to make a trip or more there this summer. I'm not a fan of sunburns as I have fair skin, but I love the scenery - the one you've provoked in my mind now - of children playing in the sand with their shovels and buckets.
Perhaps you'd consider changing up L2 with just an image of the shovel and bucket to leave it more to the reader's imagination? Something like:
Summer's sun smiles wide
red bucket topples with shells
children play in sand
Or even flip L1 & 3 around:
Children play in sand
red bucket topples with shells
Summer's sun smiles wide
Enjoyed the read,
