I dont mean to say anything bad, but just some of my thoughts ( some healthy critisism )...
when you design something like a car, apart from good looking it has to "work"...
i dont understand why the entry 4 isnt leading, i think its the only good and well thought drawing here.
entry 3 just doesnt work...
look at the front wheel, it fits there?
then the front light must be a flat sticker and not an actual light ( otherwise it would touch the wheel... try to continue the ellipse line from the wheel and see where it goes.. doesnt fit ).
rear wheel is all wrong too.
the spoiler is out of perspective, its going the opposite way.
the tyres look like they are made of plastic,
where is the left mirror?
the top and bottom versions of the car are different, look at the side window line and the space behind the rear wheel... just different. etc etc etc
Yes I read that thing above... " you are voting on the best design idea..." .. but there is no "idea" when its all wrong, doesnt fit and doesnt work.
Entry 4 is by far the best, who is the author btw?
