I did all this using Ibispaint X, a Samsung Galaxy S8+ tablet and a digital pen.

Process..

I first sketched the head..

---

At first I thought that Therosa was one of those monsters who send creepy vibes, after 30 minutes of working I looked at the original art again and found out that her pupils weren't that small, but I decided not to change it..

---

Now, I outlined the sketch..

---

After outlining the sketch I painted the parts of the character in different tones of grey..

---

Artist probably put it in grey to not get confused while paiting the base color, I don't know..

---

Result..

Putting all the shading in where I think is the right place. I'm quite impressed with how the gem came out...

Thanks for stopping by!
