That's why...Besides, lineart is just so fun!

Monk that you can always expand to colour, and make it smaller again later. From what I understand you only want to enlarge your lineart because its too small to colour. Then set the image at 300 or 400dpi (which enlarges the image quite some ^^), colour it and when its done, then make the canvas smaller again. All the images I upload here, are painted a lot bigger.

Yes, this is definitely more Wintersday and really has some humour thrown into the mix. I like!
Awesome Arya, the costumes add so much to the drawing. it's so vibrant, and much more wintersday-ish ;D Without them, the old one just looked, although amazingly beautiful, very lack of Winter
Oh and i just thought, something you may want to play around with...since you're adding the red, i think Dwayna's armour might look okay in gold
though that's just me imagining it, you'd have to change it yourself to see =o just a suggestion!
Keep up the epicness.
Well it's only a little bit of the Snowmens' awful singing 
Changed the lyrics slightly till I can find something better suited Thanks to aeronwen for the Spoiler code



i'll change her eye color, but thats something i'll do near the end. 
Hey, I'm also an AI student! Graphic Design for me, though. I actually don't like it much; I started last year when I was 23 and I've been doing GD stuff since long before graduated high school. So I kind of haven't learned anything that I didn't teach myself to do years and years ago (when it came to Image Manipulation, I was teaching the teacher shortcuts...sigh), and they won't let me skip any classes, and so I really feel that I'm wasting my time and money there.
I'm always forgetting to save constantly and sometimes Photoshop will crash and there goes all your work. I do like the reworked, piece, though, Looks nice 
Maybe your college wil take you on as a teacher!
