However, the the blood spattering almost looks like it was done in post, in many places. Just not physically realistic imho.

Nice choice with Solaris. You've got good taste. I'm a fan of both the 1972 and 2002 versions.
You have some chops son. But I see you are not a licensed user. Not sure how you get around res limit and watermark...
