@zidane888: XD Very nicely done!
@stouda01: I really like the detail in the pencil sketch and the transition to the final version. The detail in both styles is exquisite, and I love the expression.
@Minami Kaori; That's just precious, I hope you don't mind if I save a copy of that!

The border as you drew it in Post #518 seems perfect, it fits the scene nicely without overpowering it.
@Kiya; I hope you like your artbook.

A lot of work went into it and it shows, all the peices look absolutely superb and cute!
Here's an update to mine;
I think I'm close to being finished. I know I mentioned adding an Elf and a Grentch, but overall it seems like they would ruin the atmosphere and the feeling of the image. Really, the entire point of the peice is not to be funny or menacing (which is really the only two directions adding those could go) the image was meant to just depict a quiet, intimate moment between my characters celebrating Wintersday after decorating the tree...though after typing this up I just had an idea I might work in if I can figure out how to do it and have the time.
I added the shadows that Kiya suggested and also added some more depth to the tree trunks. Also added footprints so it doesn't look like my characters are just hovering there above he snow.
It would probably be cheesy to add a holiday message down in the lower right corner, wouldn't it?
