Translucent hibiscus petals

I've been watching the light shine through hibiscus flower petals from the kitchen bench for a while now, so I thought I'd try to capture the delicate patterns of the veins in the petals. The plant is recovering from an attack of aphids, so there are a few remnant bodies about (on the calyx, as I brushed a couple off the flower). It will probably need another spray to free it of them (for the time-being at least).
