@Zidane: Wow, the charr looks amazing! And I love how he is holding the little mouse. You've also managed to do fun snow effects.

Perhaps the only thing I would criticize is that there isn't much of a Wintersday feeling to it, it mostly looks like a charr playing in the snow. Still, it's a pretty awesome charr playing in the snow.
@Marsh: Awwww, kitty globe <3 And hehe, yeah, I haven't touched livestream yet because I think I'd find it confusing too. My computer can barely handle Photoshop at the sizes I draw, so adding another program to that.... will most likely make computer die.
@Nemesis: I think you should add swirlies or something. Right now the sky looks pretty blank between the gods and Melandru's statue. Either some kind of snow/magic swirlies, or dramatic looking big fluffy clouds. Clouds are always good too.

And like Death by an Arrow suggested, you could try sketching it out on a separate piece of paper or something, then see if it will work with the final piece by either looking at them with a light box or equivalent (such as against the ceiling light), or then just by using old fashioned cut 'n' paste.
@Koreena: Welcome! Glad to see you entering too, the arts and crafts side was woefully small until now.
@Fierce: Because contests tend to get all the talented people in one place?

Check out the rest of the threads in Nolani, there are plenty of talented people there who aren't around much for the Workshop.
@Tommy's: Awww, the elf is so cute. I think a slightly disgruntled face would work better, especially if everyone else was cheerful. Kind of like "why am I stuck holding this oversized carrot D:<".
@Ninja Monk: I don't think there's a way to change the lines anymore. You'll just have to re-draw it or erase the parts you don't like. :/ Or then just do the rest of the lineart in the same style. Even though Photoshop helps out a lot by giving us good tools, it still doesn't completely erase human mistakes. And the only way to get through it is to just sigh, swear at the computer a little, then just get on with re-doing it.
