try this tutorial if you have photoshop. It will help yo get the most out of your images before you upload. For example your image is 36 kb and the max allowance is 150 kb. It will smooth out those drops and make your image smooth. Hope this helps, I like your DoF.
The out-of-focus effect is so strong that it looks to me like it's been enhanced in photoshop and it's not just bokeh. I would suggest to zoom more on the subject droplet, and go with a less tall aspect ratio.
