Cupcakes and Tea

Lemon and coconut cupcakes with Milk Oolong tea. Delicious! And the mini cupcakes are so adorable (if a bit wonky because it's the first time I did frosting with a piping bag).

Critique points of interest:
The light/shadows? I know it's a bit overexposed (white frosting in direct sunlight...), but what do you think about the light and shadow patches? I liked the idea of the sunlight coming through bush branches and leaves, leaving patches here and there. Not sure if the execution conveys that  effect very well.
Mini-cupcake tips?

Thanks!
