Looks good, I like the shading. The viking's back foot looks off to me. Keep posting ;]
Keira's forehead looks a little red, looks good though. I like the way you practice anatomy and the oil bust is ace. Keep it up.
I like Mr. Hoppy and the grasshopper medic. Perhaps pushing the contrast between the shadows and highlights before you throw down color might help. Like the man hunched over looks good. Keep it up...
Nice colors on the environments from last page. I also like the character sketches ;]
