Yes, but it looks a bit like cauliflower or a segmented rock because you shaded the clumps like they all follow the overall surface of the bush, instead of being branches with their own forms.
Edit attempt:
I tried to suggest branches that look like flat-ish shapes growing slightly upward (or at least outward), emerging from the overall mass.
I also made two other changes worth nothing:
1. I hue-shifting the shadows cooler and the highlights warmer, which looks a bit more dynamic/interesting, and in the process I added more contrast so the various colours are easier to see. It's difficult to build form with colours that blend together.
2. I tried to avoid having single pixels except as AA. This makes the piece look less noisy. I tried to avoid anything resembling "lines" in general, as light/shadow are the more effective way to convey the forms and and texture of the branches.
