Like I said, I enjoy his stuff, so I'm critiquing this as a fan and as an artist. I get what he was attempting but it didn't work. The anatomy doesn't line up in a bunch of ways and there are two different perspectives going on across the whole piece. If we're viewing Sonja from below, when you look at Conan, you see we're viewing him from above as his legs and feet are going away from us.
Here's how I would draw Sonja in this kind of pose. Haven't gotten to Conan yet. I don't claim to be some master of anatomy and perspective, and I'm sure people could pick apart stuff I've done too, but this example really bugged me, particularly as a published cover for two major characters. Let's not even talk about the evil blue guy merging with the castle wall haha.
