Oh WOW! This is stunning! I adore the collar, I think the shape is amazing, but I agree that it needs a little something... beading sounds good! something shimmery or feathery.... but too sparkly! And I LOVE the colours of the skirt, especially the back bit, and I like the trains, but I agree about needing to blend the two colours of the skirt and the bodice at the front a little. And maybe make the skirt a little longer? Personally I think it would look wonderful with a full length skirt wth a bit of fullness... but that may be a crazy amount of work And that's just me
Anyway, I'm just rambling on! But in short, the work you've done so far, is INCREDIBLE!
