Newest concept car rendering

After 3d modeling my muscle car concept,I wanted to relax a little.Car sketching and rendering is the best way for me to recharge my energy.I'm pretty rusty with my sketching,so don't be harsh with your critics.Design nothing special,but it has a lots of details.My aim was practicing and rendering forms with values.Final colorized work was created with color balance effect.Sketching and rendering with sketchbook pro and with my graphic tablet.Enjoy my work.
