(1) Ahhh thank you! 😀 I tend to approach drawing faces and eyes in terms of who the character is that I am drawing, meaning that their personality or character will drive their expression. I like to start with the eyes first when drawing a face or expression since our eyes are prone to look at the eyes first when we see a face. Depending on the emotion or squash and stretch in the eyes and eyebrows will affect the mouth’s shape. (ex: a surprised face where the eyes and eyebrows are pulled up and widened will cause the mouth to “stretch” or open wide.) An expression uses the entire face to emote, even if it is a slight smile or raising an eyebrow.
(2) My internship at Disney was a blast! I loved every minute of it and I learned a ton. For me I boarded for the intern short film and also was mentored by one of the Disney story artists, doing different story exercises to sharpen my skills. I highly recommend the internship program! 😀
(3) For young artists, I would give the advice to draw what you love and keep on practicing everyday. Most of my own artistic growth came about from fanart before I moved onto drawing my own personal work, because I love drawing fanart and I am more willing to experiment with different styles and techniques drawing fanart. Keep drawing, stay passionate creating art, and have fun with what you draw 😀 Thank you for your question 🙂
