You looked good up until those last couple reps where you looked a bit 'wobbly'. I would cut the set short before you get to that point. That is probably more of a core stability issue than lack of deltoid strength.
How do you position your feet. IIRC, for a strict "military press", your heels should be touching, toes pointed slightly out.
this is a huge file, i have a great comp and it says 20 mins to dl it so just link us to youtube or something
20 minutes? Took me about 5 seconds.
Anyway, form looks pretty good. How wide do you have your hands?
