its looking good , are you working on both sides of the car ? or did u mirror it b4 u took a picture?. im not sure what model of the viper your modeling so i cant realy comment on its curves, the gaps between bodyparts look alittle big to me,
then again i think mine are the same lol, keep it up tho man its looking good

*edit
ok you did say the model of the car my bad lol

the arches at the front look as they go outa little then curve right in , the hood looks like its the front fender aswell but you said you changed it so it was like a normal hood so i cant comment on that lol.

anychance of a smoothed shot without wireframe on ?
