I've looked forward to this one since I first saw the episode maybe a 18 months ago. There were some compositional moves I made early on that I'm not 100% sure about (too late now), but all in all Towering Glacier is very rewarding to paint and I recommend it to anyone who's been thinking about giving it a try.
In particular, I consider this composition to be a good "value" in that its not very much more difficult than any others, but the bold and majestic elements come together in a sensible and powerful fashion that makes for an effective painting with a good amount of drama all without having to fuss and fiddle over a million different things. To use an American colloquialism: you get a lot of bang for your buck. In that respect, this painting took me a little less time than average, somewhere around 4 hours.
I tend to enjoy the Bob ross paintings that make clear a distinction between sky and foreground. Perhaps a result, however is that I couldn't seem to get a very good photograph of this one, but it's probably ok.
