My Heart Will Go On

Very nice. There are a few anatomy tips I have--mainly with the hands and the heads. You seem to have a lot of trouble with hands; here's a great tutorial: [link] And, of course, look at your own. Just some common mistakes people make: first, remember that your fingers have two joints, not one, and that both joins curve at the same time. A lot of animated films simplify this, but that is okay because they mastered real anatomy first and they can make it see like there are two joints even when they've only technically drawn one. Second, remember the size of the hand. If you place the bottom at your chin, the middle finger should come around midway up the forehead, kinda sorta. Two important things to remember.

Also take care with your skull construction. Here is a great guide to figure drawing, with notes on the head [link] and, of course, study real skulls and how they are set on top of the spine.

Good idea giving Rhiella's hair less highlights. The more relatable a character is, the more your reader will like them... and that includes physical appearance and hairstyle But, again, learn how real hair flows--for instance, hair doesn't form a swirly triangle at the end, as it does in one part of Rhiella's hair. It always tapers.

Finally, remember to choose less saturated colors... but I already told you about that. ^^

Oh, and one more thing--I believe the song was written by James Horner (I think...) It was only sung by Celine Dion, not written by her, and I don't think she has the copyright.

Happy drawing! ^^
