Ok…you still need to keep pushing those throw poses. I’m thinking maybe bring his right foot back a bit farther, so his torso faces us a bit more…that way he can really lean back on that foot and put some weight into his throws.
Also…I think you should move the thrower back farther…right now he’s a little too close to the “dartboard”…maybe change up the composition a bit too, with an over-the-shoulder shot of the thrower, looking in the direction of the board.
I like how the guy tied to the board falls down near the end…but might I suggest a new ending? I see you have 90 frames to spare so maybe you could put something like this in:
-thrower tosses the first three darts (as you currently have it), and the guy tied to the board is let down
-as the thrower gets ready to throw a fourth dart (he takes a bit longer to throw this one)…the guy who was tied to the board tears his feet out of the last straps (thus completely releasing him from the board) and stands up, waving his hands to stop the throwe (who of course can’t see him)
-the thrower throws his last dart (without knowing that the other guy is standing in front of him, waving his arms to stop frantically), and either…
a) finally NAILS the guy who was tied to the board, sending him flying up against the board, like an insect being pinned down.
b) throws the dart but misses once again…but not before the guy who was once tied to the board does an elaborate last-dodge (I dunno…maybe he contorts his body in a really awkward way)
c) throws the dart, but the guy who’s been released CATCHES it in mid-air (superhero-style), and throws it back angrily
Just my $0.14
Keep it up!
