Car Sketches

Some car sketches I made at work. Some are a little old, from earlier this year, while some are very recent.

I've just started trying to use to points as perspective references, as you can see with the top one to the right, and bottom right one. I can already see my sketches improving using this technique, as proportions and shapes are coming out better. These two aren't my best yet, but I feel they're decent.

Drawn with pen, modfied in Photoshop to darken the lines a bit.
