You did manage to find some very nice color, and there is some good potential with this photo. It also appears to be a light overcast day which means that the sky is probably not very interesting. So I completely agree with your decision to exclude the uninteresting sky and just emphasize the colorful trees which are very nicely depicted in this even light.
My major concern with the photo is that there is no prominent subject that draws the viewer's attention in the scene. The scene is mostly middle ground and background without any strong elements in the foreground. I believe the photo might be more successful if you had some of your fellow hikers in the foreground, perhaps in profile looking into the scene. Other options might be to approach some of the ski center equipment or a trail sign so that it looms large in the foreground. Or perhaps you could find some isolated and colorful trees to include in the foreground.
As forestgnome noted, the ski lift adds to the story of the photo, more than just having the beautiful color. Indeed if you were just to zoom in on the portion of the scene that includes the ski lift, trail sign, and ski gun with the blue base; I believe you might have a more interesting photo. That portion contains some of the best color. We would be able to see the individual trees better, and there would be a stronger focal point for the viewer.
Ski Centers are great places to view the foliage as you have more widely open views than on the more narrow hiking trails. Overall I commend your choice of location and your good use of a bright overcast day.
