yes, you can tell. it always baffled me that guys with great physiques would pose so bad. I focused on transitions and such when I was young. after the early 90's I would pick a song the night before and wing it like you. this is something you can get away with if you can nail the actual poses and have some semblance of flow between poses and focus on the heavy beats of the song. everything looks like a choreographed routine if you can do that.
I agree,have seen some monsters with the whole package place well behind lesser physiques because they had no clue how to display their body.
I always pose to a Santana song....doesn`t matter which one as I don`t really choreograph it anyway,but I love the guys music.
I`m good at transitions....I did practice them here and there just to give the poses a more graceful look if you will.
I tilt my body a bit like Zane in some shots,and like Nubret and Arnold,I try to hide weaker areas if possible.

This year I am actually gonna` pose my ass off from the beginning of my prep...no stupid dancing or fake smiles,but Ed Corneyish if you will.
If I can pull this off with my already pretty decent posing,I think I`ll place well,because I always get in shape by giving myself plenty of diet time.
