If you want it to be a coupe, yeah, the front should be longer, and you have to take out the C pillar. If you don't, it's gonna look weird. And I think you kinda messed it up with the rear wheel, because it seems like you shortened the wheelbase(I know you didn't, it just looks like that). Front is ok 
Idk, add a small overfender in the rear or something, just follow the original lines and move the wheel arch line up, so it fits the wheel, just like you did in the front. Oh, the tow hook is too big
