Poll: Help me to pick a theme for the next pinup set (Patreon)

You might remember the sci fi pinup set I did a year ago.

In February I want to make a little break from my regular commissions, improve my skills and produce a new bunch of detailed pinup artworks within one theme. There's a lot of themes I enjoy but I would love you to help me make a choice among these: pirate, ninja, stampunk.

Vote here, please:

I will be selling them as YCHes at FA for $300 each (they will be elaborated and require much more work than regular commissions), but I will firstly put the poseholders here, so in case if interested, you, my patrons, will be able claim a slot first ^^
