I have a greyscale printout as a hard copy reference.
Thanks for the suggestions. . . I’ve been fooling around a little with the shading, but my attempts seem so fake.
I will try turning it upside down. Might give a new perspective (fresh view) of the drawing. Good idea . . . I like it.
Metsys, I have terrible eyesight already. I just need to take off my glasses . . . I no need to squint. I will try this one too. I might also try both suggestions at the same time.
My rocks aren’t exactly like the photo, but they are very similar (ie small waterfalls . . . rock shelfs . . . etc)
