Not sure about that one, but maybe Zyrus has one seeing as he recently modelled Riku himself.
I thought i'd post the process I use to get good refs from anime, so other people can make them
(first tut :O):
How to make full-body refs from anime:
What you'll need:
-The anime you want to take the ref from.
-
Fraps ideally, or any screencap (screen capture) program. You can disable video acceleration and use the PrintScreen button if you *really* must, but it'll lower the quality.
-
Photoshop ideally, MSPaint can be used too.
I'll be writing this for MSPaint, Photoshop users should be able to work out how to do it from this, plus, they can use the layer blending to match up the layers better. It's faster to do it in PS too but anyway, everyone has Paint.
A lot of the time in DBZ (i've seen it in other animes too, but i'll be using DBZ as an example) you'll find the screen scrolling up (or occasionally down) characters for dramatic effect. For instance the introduction of a new character or form.
As it scrolls up, take four or five screencaps depending on size, then open them in Paint (or Photoshop), then copy and paste all of them into the same Paint window so it's something like this:
Now move the segments working from the top down so that they overlap each other and all the lines link up. Everything should sync up nicely unless it was moving in the anime (aura, dust clouds etc).
Finally trim the image so you get rid of the blank space and save.
You're done :]
