Playing a big hand live when you just sit down

This Friday (Saturday morning), I decided to go to play some 2-5 @ The Venetian, I got there around 2AM (nice starting working hour heh), and ask for 2-5 NL, there was a table with 2 seats open, so they sent me there and looking the stacks at the table I decided to buy $600, at the Venetian you don't need to post your first hand, so you get to play it for free and since I was on late position I decided to start playing. I got Kd3d, I was still busy with my wallet when the action came to me, nobody has called, so, I decided to just play the hand and call the $5, nobody called, just the blinds and we got to see the flop.

Flop: Qd7d4d

Wow, really nice for a first hand, but since almost no people in the pot and no preflop action, usually you don't win much, they checked to me and I of course checked. Turn was the 4s, LB bet $15, BB called the $15, nice, somebody had to have something, so I decided to raise to $65, why $65, since I was new to the table, they have no image of myself and I wanted them (or the one of the two with the better hand) to think I was buying the pot and called me if they have a Q, well, little blind didn't disappoint, but instead of calling me, he reraised to $115, BB folded; interesting, what does he have?, I saw no point on raising, so I decided to just call the $115 and see what happens with the river, river card was Kh, so we have a board:

Qd7d4d4sKh

He then decided to bet $250, mmmmmm, wait, a Q does not make much sense, so maybe he had a 4, a flush or a boat; or maybe he was full of air, continuing a failed resteal on the turn, betting that much with a 4 didn't make much sense either for me, if I was weak, that was way too much if he wanted me to call, so, flush, boat, air, I didn't see much value by reraising, so I decided to just call. He had 10d3d and I won the almost $800 pot.

Probably I would have played differently if this wasn't my first hand at the table, but I was pretty content with the way I played it, some may say I should have gone all in after the $250, but I don't really think it's the best play in the long run, since most of the hands that call my all in with that board (boat, A high flush) had me beat.

It was a good thing to start winning that night (morning?), since for the next 3-4 hours, I was not winning anything, not flopping any pair, lost the minimum with AA and KK, lost a turn all in, when I was a big favorite, all that crippled my stack, but I didn't lose my temper, just wait and wait, and eventually things came my way and after playing some 9-10 hours I scored a pretty good session.
