Well, I think your digital part is really good, thugh you should try to make it a bit more.. glass-ish. Not so much blue, and lay some more weight ind reflections. Try to add more black and white, inside of the ice itself. Really good work though! Couldn't do it better myself!
And the traditional one, is also really good. I especially like the house, and its perspective.
The trees is maybe a little too edgy... I don't really know what else to say... I doesn't draw trees myself.. >.<
I hope it helped, and keep going with the good work!
