Ok... played it. The car physics are fantastic and biggest fun in the game.
The game itself could be fun, but for now I think you tried to make it too realistic what I think is boring.
Endgegner is right, that the clouds kill the frame rate. You can have as beautyful clouds as you want, if killing the fps like that it´s useless.
For me it would be much more fun if the gameplay would have more design. THat means:
-the cloud in the first mission is always positioned in a far distance and I have to reach it before it disappears. The faster I am the better cloud fotos I can get. For the fastest time I even can get lightning fotos.
- I can drive across the whole country, but off the road its getting bumpy and if cops get me I loose money or time or the game ends.
- On the way are specials to get faster there, like natural jumping ramps over obstacles like fences and dustbins.
- Other obstacles could be forests
- On the way I would also have to avoid flying around dust bins, barrels, wood beams and such stuff
And for good fotos I get money to buy better cars, cameras with zoom and girls
Just my oppinion, I hope it helps.
In later missions I have to get a cloud which is far away and flying away, and if I drive into too many obstacles will loose it. And for final missions the player could be chasing hurricanes/tornados.
