Yeah, valid crits, though I like the head bob, unrealistic as it may be... I might fix the selout, as it's a bit wonky in places, though I like the effect, so I might try to salvage it.
Oh, and the other ones were just posted to show what I'm doing lately. You can C+C them if you want, and if you provide an edit, I might even update them. I just don't want to spend hours trying to get them right...
Thanks for the crits everyone
