Thanks for the critique~!
I see what you're saying about the armor, I was trying to pick a proportion that wouldn't look too large and gaudy for the character. The color actually looks a bit darker in this picture than it actually was because of poor lighting, but I do intend to have it be lighter in future models. When I remake it I will have your suggestions in mind.
As far as the collar goes it was a rather thin line to tread as far as how large to make the opening. I wanted to have it look as close the picture as possible without having to struggle to get it on (pictures don't tend to take functionality into account). But I see what you're saying, the opening on my collar did end up a bit big. I'll try to fix that on the next dress!
The gloves were pretty tricky. Getting gloves custom died is very difficult in the area that I live and really overpriced, plus they generally want you to provide your own gloves, so I died them to match myself. All of my glove-dyeing horror stories aside, I'm happy with the color. I do share your concern about the length though, they seem a bit short. Getting new gloves may make my list for future alteration, but finding gloves longer than this that are still dyeable will be quite the ordeal.
In some pictures they don't seem as bad. (In this picture you can also see the gold dangly things - I did in fact make those. I didn't think to check if they were visible in the previous picture, sorry.)
Making the armor bigger may decrease the length problem with the gloves I think...
I see what you're saying about the makeup. Originally I hadn't used as much blue, but when I had my mother do a once-over and fix any problems with it she added a lot. Next time I will make sure she uses more black than blue. I also might consider using false lashes, since real lashes tend to disappear on camera regardless of how much mascara you use...
