Dark Signer Ruka

The start of my Signers as dark signers series. I had never drawn Ruka before so... this was a major time consumer! All in all I like the outcome. I was going to draw a darker version of Ancient Fairy Dragon but I failed to have the motivation to do it. I know Misty is already Green but Ruka takes her place. Here's the switch ups I came up with.
Aki - pink dark signer [not yet shown in series anyways]
Jack - Rudger
Yusei -Kiryu
Ruka - Misty
and since there are no more signers.
Rua - Demark
Crow - Bommer

there. They have all been paired up~ :3 So if I actually get around to them then you all owe me a cookie, since I rarely ever finish things I start
