Supernatural Commission

First of all - I LOVE THIS! The expressions are absolutely perfect, and I love how well you captured each character's distinctive hairstyle (particularly Sam and his awesome sideburns <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>). And the composition is so dynamic! However, there are a few tangencies that mess with the perspective - Dean's hair and the rope; Sam's knee and Dean's knee - that almost make it look like Sam and Dean are on the same plane even though Dean's clearly supposed to be a lot farther back in space. Also - the bottom of Sam's jacket lines up with top of his leg and his back pockets are hitting the lower edge of the frame, and it kind of makes his ass look huge. (I'd make his jacket longer and move the framing down.)
One more minor nitpick - Cas's tie is supposed to be blue!
Other than that, though, it really looks great. <img src="e.deviantart.net/emoticons/b/b…" width="15" height="15" alt="" title=" (Big Grin)"/>
