manmade forms

artist pen and pro marker

this car drawing uses the promarkers well to not only show tones around the car but also help it form and shape, the promaker have also been used to make an impression of inside of the car as we can see into the windows the shading used helps create the impression of the seats and windows. we have some forshortening withing the image as we can see the back wheel is smaller in comparison to the front wheel. there is some highlights on the car created by leaving some areas unshaded these highlights become areas of interest for the viewer and can also lead them across the image as an implied line for example the white hightlight at front of the car and be followed to the one on the bumper and then across to back of the car. 

image 2- car

This image has good form and shape such as the grills at front of car and some areas on wheels however these areas aren't that detail. the shading in the car is very light the give quick impression of the inside of the car.

image 3 truck

this image has more detail compared to pervious two image as the car has detail such as wheels, the designs on the car its self, even the rolled down window adds much greater detail. The light shading on the windscreen also helps to create the glass effect and  allow see into the car giving it a more 3 dimensional feel. We see some good use of tone at front of the car we see darker tones at front with light tones which represent highlights in the car this creates an area of interest in image and create implied line as viewer eyes goes will follow change in tone.
