A few cars

[Heermeier]

Hello peoples!
Need your opinions and advices. Something to improve etc.

I like your car!

You could turn one of the wheel hubs, because the front and back wheels wouldn't be in the same position unless it was 4 wheel drive. It probably needs a bit of anti-aliasing work done on it to avoid the noticeably jagged edge too

what are the grey bars on the back seat?

Thank you Jehannum, but anti-aliasing needs a lot of work and im not sure about much more better result. Grey bars, oh, its a safety roll-cage, my goal - hundreds of racing cars.

with both the red and blue cars, are you sure the roll bars seen in the boot window are drawn with the correct perspective? I am curious if you had a "source" to work from that I could see, as I'm struggling to find images on google from the correct angle, and I don't own any toy cars.

Something about both is bugging me immensely haha. The red one has the left (upper) bar going into the bumper, but the right (lower) bar is going into the side of the vehicle. With the blue one, shouldn't some of the right (lower) bar be visible in the boot window, as the left (upper) bar is visible enough to suggest the other would also be partly visible.

I use 3D as reference, but in this perspective its looks not good, you right. Thanks!
