Straight Flush draw after flop.. Guy got mad at me for my play.

[Toddy]

Last night I'm playing in a tourney. This guy was bullying around the whole table. I had T1700 chips left, and the avg stack was about 3500. Im the BB. SB (bully) raises to 400. I have 78d, so I call. Flop 5d6dAc. Guy bets 400, and I go all in (which i think is the right move with all the outs and I'm really shortstacked). He calls w/ A5. Turn is a blank and the river is a 9 for my straight. The guy wouldn't stop talking about how bad my play was. What do you think? I had a boatload of outs and 2 draws to get it.
