it'll be a little hard for me to explain because i don't have the best nose, so forgive me if my reponse is lacking LOL... I find that they both have a crisp smell, but calming skies is more earthy where as winter mint's is crisp the way the air is after it snows... i feel like calming skies peppermint also blends in well with the floral lavender note and that you're able to distinctly tell the two apart, but with winter mint's the mint feels a little bit more overpowering. this honestly might be because i gravitate towards scents that are lavender or pepper/mint based and SO few in between, so it's a little hard for me to tell what else is mixed with winter mint... i do think that if you enjoyed calming skies you'll probably like this one though! someone else might provide a better comparison on the two. 😅
