I think the orchestra sounds just fine (perhaps there a bit too much verb on them IMO). I feel many of the other elements aren't in their place, the drums are lacking bottom end oomph and you could easily get away with more compression on the vocals (perhaps a bit of distortion à la Spike Stent to keep them on top of the mix). As a learning process you probably ought to try to match the sonics of Hurts' first album Happiness (which is better sounding than their second effort, more punchier). Bright vocals, punchy drums and wide orchestration. Rarely it's the orchestra itself that sounds punchy per se but many of the other elements in a cinematic pop song.
My personal favorites in a "punchy orchestral" genre are Björk's Homogenic and Vespertine albums. In both albums it's the drums (more in the former) and especially the vocals (which have been given an intensive sound) which make that punchy sound IMO.
