I like to use grids and used a grid for this photo- is this off limits? That's how I was taught to draw all throughout school...
Your comment bothered me much more than it should have; probably because it's very belittling. I ended up comparing my drawing to the original picture. What I drew has a lot of inconsistencies with the original. It's close because I used grids to try to get the correct sizes and placement, but not perfect like a tracing would be.
Not that it really matters to you - but to demonstrate the differences, I went ahead and traced the outline of my drawing and placed it on top of the original picture (with the background erased):
If viewing as if you were sitting in the car:
-Front left wheel slightly smaller & not the correct shape; rims & spokes do not match up
-Front left fender angle extends slightly further and juts upward on horizontal plane and dips into a lower angle when connecting to running board
-Front right rim and spokes don't match up
-Missing front right fender completely
-Front right headlamp larger
-Grill & hood ornament pushed forward
-Left headlamp near windshield is slightly larger
-Shape of the cab is off; highlights in wrong place
-Missing door handle
-Running board is wider and connects to rear fender at the wrong angle
-Left rear fender slightly larger
-Left rear rim (white) takes up nearly the entire tire - meaning the tire is too thin
-Back of the cab ("trunk") juts upward
-Lower part of windshield is at the wrong angle
-Supporting poles for the convertible top are wrongly placed and/or at the wrong angle
-backseat pushed up (larger)
-Convertible top much larger
-Window in convertible top doesn't match up (higher, smaller, wrong angle)
and probably others that I missed...
Tens of thousands of drawings are way more photorealistic and accurate than mine. Take this for example: https://www.reddit.com/r/Art/comments/40x0cg/blonde_chick_digital_4k/
