Well, since you ask for opinion.... Is this some thing you like to see a car manufacture (Honda) to built, or exercising your artistic ability?
To view it from pure design point of view, as a potential production car...
The front lower spoiler will never work; the slightly raised F1 style nose to accommodate the spoiler will most likely not meet the Federal crash regulation; so is the height of the front bumper. The rear bumper probably needs to go since we are about to enter 2008 (Even Honda delete the "stick out" rear bumper with the HSC). If the raise nose could be made to pass the Federal crash test, you may face aero issues since that is mainly design for open wheel cars. Also, the front wing is at an wrong angle to push the car up instead of down? I'm not an aerodynamicist, but I assume if it is usable, Ferrari or McLaren would have done it.
By measuring the drawing, the wheelbase seems to be a little long (You can put add measurement to the drawing so people know what you're intend is). Also the tail end after the rear wheels is also little long. Do you intend to have the trunk in the front or rear?
The lines on the door suggest the famous Lambo Scissor door design, which Honda will never accept. And it could also be a safty issue if the car flips. The rear hatch glass probably shouldn't cut into the door, or vise versa, unless cut-over is going to be painted black to match the line, but it is kinda weird to have it like that if the windows are not tinted. There is absolutely no reason to have a divider between the door glass and rear hatch, which leads to lack of visibility from the side windows. The side mirrors probably should angle towards the other way to avoid aerodynamic drag and wind noise issues.
The rear spoiler made it a little ricy, which in term, made this design more of a NSX with a wide body kit than an actual possible production car. In my opinion, the drawing is very beautiful (Under my reasoning if used as a concept car), but the spoiler is kinda out of place.
And need side skirts.
However, as a concept car, it is a beautiful design. It does have a Zonda and HSC flare to it, which is welcome. It will make a very cool car in Grand Tourismo or a futuristic movie.
This are my sincere opion since you ask for it. If the intend is to be a production car, you can easily make this drawing more realistic.
Nice job.
