To be honest, the reference pic you used for Dana with glasses is awful, good job on the concept of trying to find content for new gimmicks/attires, but screencaps are not the way to do it when they are low quality. For now, since there's not much reference pictures on Dana with glasses, use the other face texture, get a picture of similar glasses and work with it:

I slapped the glasses on top of your screenshot, didn't change the hair but you should get the idea. I think you still have a lot to improve on skin and attire, they lack details, but your face work is quite solid.
By the way, as people said before, focus on one thing at a time, it won't help anyone but you in the end, from what I've seen so far, stick to finishing either the Dana or the Charlotte mod.
