Spark Plug with HDRI

Was using half an hour to model the spark plug, plus another half an hour to setting up the HDRI and texturing.

Well, same as the "goggle". I didn't add up the anti-aliasing quality to minimize my render time, yet, it still took up to 3 hours to render this image.... ><""

Hmm... I got this spark plug's reference from a forum. Thus, I want to make a test on HDRI with it as it's made of metal and can easily show the HDRI elements.

P/S: Depth of Field added, but low quality image causes the blurred part become very pixelize... Desperately need a new pc now....!!!
