I agree the right side version looks better.

I'd suggest making the "contour lines" round the tops thinner and less distinct - closer to how the hatching is drawn, as they seem too dominant otherwise at present.

Not sure if it might be worth trying with a tool that generates longer hatching lines instead of having to draw two or three sets together for the steeper areas. I've a feeling the law of diminishing returns is liable to set-in with too much experimentation, however.

Glaciers might work with a more transparent version of the fill you have showing the seas right now (not sure how the style generates that appearance, so this might need extra work). The original book map looked to have a scattered series of small pale blue dots and tiny circles to show the glaciated tops.

The book-map lakes used a lot of lines drawn parallel to the lake banks right into the lake's centre, more or less, which was also how the seas were shown, although that looked uncomfortable to my eye, so you might want to try that, or maybe tone it down a bit.

You are not alone in this - had CC3 10 years now, and only discovered this was possible thanks to one of Monsen's video tutorials where he showed it, which I think was the year before last now (that dratted pandemic and its time-dilation effects again!)!

@Fersus - If you have the solo rules ("Strider Mode") for The One Ring, which are only available as a PDF still, as far as I know, those do add some more journey options which could be adapted for group play, or perhaps would help spark ideas. I've not played TOR yet, but it did strike me when just reading through all the rules (I have everything that Free League have published for it so far) that a lot of the random result tables generally were too short, so would be apt to become repetitive. I like Ralf's use of pre-prepared options along with the random rolls to make things more interesting overall, since as GM, you can't always come up with some worthwhile variant every time the same roll comes up otherwise.

I may be misreading the hand-drawn version, but aren't the trees meant to go right across the mountain peaks as well? On the CC version, it looks like they're almost all bare rock currently (judging only by the coloration, not whatever that grey fill style is meant to represent).

Better health from here on in, hopefully, Autumn.
