Eventhough I am from Europe I cannot help but loving the good old muscle cars. I started drawing a few muscle cars a couple of years ago and I love the challenge this drawings gives me! Getting a muscle car drawing right is not always very easy though.
One thing that I often have a hard time while drawing muscle cars is to get the proportions right. These classic car shapes are quite complicated to get right as you might have experienced from drawing them yourself.
After many screwed up muscle car sketches I am finally getting the hang of it. My advise is to just focus on the general lines of the shape. And then just try sketching them, and don't be afraid of redoing it until you are satisfied.
Doing Camaro drawings is always fun, they are quite challenging because of the shape, but the final result is usally worth the extra work put into them. I also enjoy doing Mustang drawings, it is something about the older ones that really scream "drive me"! To make a good Mustang sketches usually takes me around 5-10 hours to get them to the level Im happy with. While just to sketch the general shape of a mustang shouldn't take longer than 1-2 hours.
My best advise on how to improve your car drawings is simply to spend more time on them. For example if you are not fully satisfied with the front lights, don't just continue with the drawing and hoping that the lights will get better by some magical touch. No, look at the lights and don't give up on them until you are fully satisfied with them, then move on to the next part of the car drawing.
If you love Muscle Cars you should get your favorite pencil and sit down with a clean sheet of paper and just relax and start sketching your favorite muscle car. Don't give up to quickly, just focus on the general shape of the outward lines of the car and you will soon see how the sketch is becoming better. Remember patience is the key to success when drawing a muscle car.
