This illustration was, for me, a really fun exploration of texture. I enjoyed building up the grubbiness of all the surfaces in the alleyway. I also really like subject matter that is both whimsical and dark, and I think you'll find both elements at play here. If you look very closely you'll notice a pair of evil, monstrous eyes staring out from the window, but never fear! What appears to be an ordinary alleycat is in fact a benevolent guardian angel, here to keep the little runaway safe.
Some preliminary sketches.
I used this little rabbit figurine to test how the shadow would cast on the wall behind under similar lighting conditions.
