Masquerade Gown Sketches

It seems I will be attending a Masquerade next Year. Which means I need to make a dress for the occasion.
Since I usually do not Larp in this setting, I am building a one-time character, but I am planning to use the
gown for my sorceress character, Seren afterwards. Which means lots of green and purple.

I already have the corset and skirt, so I can focus on making the mask and those impossible sleeves.
