I have not been here for a while …i had long holidays
@Greenguy2201: thanks BI stands for Blender Internal Render …realistic results are bit harder with BI maybe try to play with Cycles …but probably with every render engine are keys …good lights/materials …but i am not expert 3D is just my hobby. Just keep practicing with tutorials.
@ tyrant monkey: thanks man ! i am glad that you like the renders …i agree with the car model it could have been done better…next time i have to start with posting wires so someone like you can point me in a good direction with the topology .
