The only thing that I really didn't like from white was 5.Qe2. I think the Spanish autopilot dictates that you simply castle at this point instead of defending the e-pawn. If he immediately takes the e-pawn with his knight, you should be able to gain the material back in a few moves by exploiting the now half-open e file and black's uncastled king.
Aside from that, 5.Qe2 just looks awkward. I think that you were reluctant to defend the pawn with moves like Nc3 and d3 because Nc3 would interrupt the c3d4 pawn break in the center that is typical of the Spanish, and defending with d3 would lose a tempo. Still, I really hate placing the queen on the e2 square during the opening because it opens up tactical lines where she can get harassed by a knight landing on d4.
The centralized king at the end was real nice.
