I'm procrastinating, there, though, because...hands! Hands! Lots and lots of artistically baned hands! It's going to be a nightmare, even though it'd get me just one drawing short of being caught up. After that, the plan's to do her socks and shoes (day eight), her Dark Ruby shorts (day nine), her Dark Ruby jacket (day ten), Dark Ruby fingers (day eleven, though may change to be day eight to be with the other hands), Blood Staff (day twelve), Lord Ventrella outfit (day thirteen), and undergarments (day fourteen).
After that, I've run out of ideas to stall, so everything I do from there is improvised. I think day fifteen will be Ruby in casual clothing. Then, I think day sixteen I'll draw Ruby in all her gear, but without Angel Wings drawn. Day Seventeen, I'll do one with Angel Wings. Day eighteen, I'll do Dark Ruby. Day nineteen, I'll do Ruby as a lifeguard. Day twenty, I'll do Lord Ventrella. Day twenty-one, I'll do a casual Ryan.
I've run out of Ruby-centric ideas I could use, so from there, it's whatever I fancy, but 21 drawings will be a win in of itself, even if it's not the 21 I'm aiming for, so I'll take things one step at a time.
In the mean time, I considered blogging about this tomorrow, but it's been on my mind for a while, and I decided I might as well knock it out today. Basically, all the characters need heights, and I don't think I have that info beyond, "is generally tall" or "is generally short", so here's me attempting to get some numbers.
The tallest Riders are Gary and Whitney, both standing at an even 6' tall. Ruby, though 6'2 when Ryan, shrinks to be 5'10" when in her magical girl form, and she's the second-tallest. Behind her are Sally and Hannah, both coming in at 5'8". Vili's behind that, at 5'6", but the real prize for shortness goes to Whitney's partner in battle, D.D., who is 5' tall: basically, pint sized. Amy grows as the series progresses, going from 5'6" up to just shy of 5'11".
As for Herald, he's 5'11" himself, whereas Dale comes in at 6'1". Dion himself is 6'2". That's not even close to all the characters, but it's the majority of them. Keep in mind, I may adjust this, but this is approximately what I was going after height-wise. Whitney's tall, Ruby's decently tall herself, Sally's up there with Ruby but not quite her height, D.D.'s petite, and the others just kinda fall into place from there.
