A while back I posted up this picture:

The key bit I wrote below was this: "On the left side I've drawn her in a "modern" style, or at least as close as I can get to it. It's a pretty common style used today. On the right is that look with a few tweaks that I think help out. I don't know if I'd call it a semi-retro look, but I did use some stronger elements, like lower eyelids, more detailed nose, etc. That's common with older designs, but I feel like it helps me to do more interesting things with expressions."

Based on the comments, and based on my own thoughts, I've decided to explore the right side style some more. I'm not trying to make a "retro" style, but rather, I want to build on various elements that I think work well for my art going forward. A more defined nose, and extra details help me make a more expressive design- so that's where I need to go. I want to be careful and make sure I'm still keeping an appealing look, however. As I'm not a professional character designer, I need to be careful in my approach. I'm no expert!

The character is original, if you were wondering.
