Wow, only two years!? You're fantastic already, but there always is room for improvement. I'm trying to get better at digital painting, too. It's fun and relaxing, but also very difficult. Lols. Best of luck to you.
I especially like how the colors evenly blend into each other, and how the color selection gives a sense of warmth, which seems appropriate for the theme. The shading is exquisite, very lifelike. The textures of the faces and hair are very detailed, and the facial expressions are realistically proportionate and created very finely. This is, overall, a wonderful piece and a very rewardful job.
Oh yeah, and how on Earth do you make something like this??
