As usual, I love that you stuck to your style heavily!
With Rought, I actually think the bells are perfect for the 'frozen wasteland' theme, almost like a cursed Christmas. The instrumentals and scraping sounds fit that crumbling aspect shown in the original image.
With Frozened, the guitar is a great and bold addition. I also like the bell carried from the first to the second track. Overall, I like your take on the theme and think you leaned into the'wasteland' idea well.
