I discovered the Loomis Head sometime in late November, but I just can't quite seem to "get it." Something always seems off. Any advice/tips from the people of Proko on getting the Loomis Head right?

My first "pear" attempt. Pretty sad looking but I'm happy with it. I also bought the Secrets of Shading course to go along with this because one thing I really struggle with is lighting, shading, and shadows. Hopefully between the two courses I can become competent enough to present my effort to the world lol
