I appreciate the tips guys!
First, I can't believe I painted his lips as teeth. I could have sworn they were. Ofcourse, after you pointed it out, I can see it. Oh, well. My painting skills are definitely a work in progress. I understand what you guys are saying about higher contrast. I think my issue is I don't take into consderation the distance they will be on the table. I have tried constrasting colors for some of the more prominant highlights, and I always find myself saying "That looks goofy". So I end up muting them, and making them look more like I think they would look "in person". Lighter and darker shades of similar colors etc. I am working on it though, and forcing myself to try different ways and techniques. In an attempt to further my education, and eventual skill, I always try to apply advice other, more experienced, hobbyists share with me.
