Thanks for the comments and opinions. The borders giving the boxed in feeling is ok. This girl is a very strong feminist. The red stripe can be a sign of her views and attitude. It's also a sign of freedom for me. As I explained in the "work in progress" thread, I've never been this bold with my work. The red stripe creates an abstract element because it does'nt form to the body, but still think it works. It may be a small step, but I see it as a way to enjoy my work and to take a chance, even something so trivial, not being concerned if someone else will like it. Going the same red for the borders would have been too much, so I went with a rustic red which is used in the body and the base color of the gray background.
I will keep the borders smaller, so I guess the size is now 21X32".
