The older one is 'cooler' (simpler and more archetypal and more in keeping with the current zeitgeist) the newer one is more human, nuanced and emotionally layered. I prefer the new one of course, but
the body language of the prominent figure is womanly, which is antithetical with the material (this is why people would prefer the old main character with his legs open mighty stance and huge muscles) and his head is slightly too big for his body, giving him a somewhat 'childlike' look, so he looks weak and his expedition doomed. The birds of prey in the background make it seem like they will die soon and they will eat their corpses.
The secondary human figure is unfortunately cropped and placed in the background, it seems as if he's half-a-man, left on the rockside. Showing his solar region and some of his legs would help disambiguate.
Pay extra extra extra attention to hands and how they work and what emotions they signify (look at Frazetta again). None of the four hands in the picture are drawn correctly or emoting something clear. It's the 'action figure hands' syndrome, I tell you this because I often have similar problems.
Keep in mind all my critique comes from a good place inside. I'm always paying attention to what you post and have a recollection of your progress, junkboy. In my opinion you've grown a lot and you can become an absolute master at this if you put even more hours into fine-tuning your construction and anatomy. Your rendering is more than solid and you have a wide range.
Since I posted, in the case people don't know about my webcomic, here's a recent page
Pencilled by hand, inked and airbrushed in Manga Studio.
This is the last chapter, will be posting the last two pages in the next week, so it's a good time to read it from the tops
here.
