Definitely! 
For a start, a close-up, so that you can see what’s going on:

These were rendered in roughly three stages.
For the basic folliage I used one of the custom photoshop leaf-shaped brushes. I decreased its roundness at about 20-something%; Slightly angled. Size jitter is optional; minimum size diameter at 30-40% angle jitter around 10%. Scattering, both axes, ca. 250-300%. Other Dynamics: Opacity and Flow at Pen Pressure. All these values can vary of course.

I went on erasing and blurring some of the edges here and there to remove the stamped like effect; I next switched to Painter, where I used the Pepper Spray from the Airbrush menu, with the feature slightly increased (so as to have larger specks). I kept my pen tilted so as to have a larger spread. This was used relatively sparingly and I erased a lot of it once I came back to Photoshop.

(50% original size)
Photoshop again, blending in; not just black or dark colours now, but also colours I picked from the sky and environment, or intermediate tones. The brush is a standard hard round brush, roundness decreased at about 50%, slightly angled. I changed the angle several times while painting – this was the same with the leaf-shaped one. Size jitter about 30% (Control: Pen Pressure), Angle jitter 14% (Control: Off), Scatter: both axes, ca. 500%; Other Dynamics: Opacity and Flow at Pen Pressure. Again, I’d periodically adjust these, especially scattering.

Hope this is clear enough. 



It took me 2,5 hours to complete this.
