Rain garden visualisation - Unfinished

The visualisation attached was created to balance my dissertation abstract in my assignment portfolio. It depicts the rain garden module detailed in my sus tech project, which has transferred the research I did for the diss in the first semester. The visualisation itself is not quite finished, as the gravel is not completely rendered, however, I am pleased with how it's shaping up.  

The planting I have depicted is accurate to the planting plan I have created for the assignment, including Agapanthus, Oenothera lindheimeri, a Lonicera nitida hedge, Sanguisorba and Edgeworthia. Along with the main Betula utilis.
