I like v2 of the first one... it's pleasing to my eye But I don't really quite like any of the edits for the second stock... Changing the color of the lightening really made it less interesting... I would try adding more fluff to that one, it seems you didn't edit much...
I did more in the Thor one that may not be apparent. Sharpening/Blurring (Focal work), edge overlays, gradient overlays, and smudging. (although the smudging is REALLY hard to notice due to so many extra overlays) EDIT: But thanks for the comment! I do realize the second is a lot more bland, simply of filter work. Plus no one seems to want to comment on my work it seems, lol.
