I've been working on this for the past month or so, and I tried a bit of experimenting with Flemish layering techniques. I'm happy with how it turned out. It's got a kind of grungy look to it, which I really took a liking to as I worked more and more. Painting leaves is hard work! I had to find a fine line between going insanely detailed and losing my mind, and giving just enough of a hint of the fine details to achieve a high level of realism.
This was a lot of fun and very rewarding, so I'll probably do some more flowers in the near future.
