As for the skirt...I would lower the highest part a tad and put some gold accents in there somewhere to tie it into the bodice...That collar is freaking amazing...maybe some red and black feathers coming off of it or some detailing around the edges. ?
On a side note.. I just read your profile. I would like to say I commend you for having the strength and courage to keep crafting! I wish you the best. ...and if you ever want to sell these ....Etsy is your friend.
