This intimidating creature has a vibrant green body that is covered in menacing black scales. Its bright yellow eyes seem to bore a hole into you, and its jagged teeth are threatening and alluring at the same time. The serpentine body is coiled tightly around a large rock and its tail is wound securely around a nearby tree, making it look both powerful and majestic. When coloring this picture, I'd suggest using dark, bold colors to bring out its intimidating nature. You could use blues and purples to bring out the darkness of its scales and lightly trace the outlines of its body and scales with white to make it stand out clearly on the page. A nice golden brown for the rock and a bright emerald green for the tree it is wrapped around would help it steer away from looking too dark and improve the composition overall.
