Inner Circle - Flower Friday

These petunias have a circle of colour right inside. BikerBear's theme for today's Flower Friday is 'Circles'.
I tried some macros using the reversed lens suggested by Emma Davies, #A Year with My Camera. Some interesting results and will practise some more to try to get the focus right (see extra). 
We went to the last home football game for the season tonight. A pretty poor effort - we lost 0-3.
