...christ, tetchy.
I don't think anyone was saying what you'd done was a representation of your work or skill level, we were taking the piss out of our own ability to do 'automotive design', which is evidently ... nada. Obviously this is your area of business, you don't have to justify yourself to anyone (unless you feel the need to.. but this is the internet, so of course, you will be judged). Welcome to banter, light hearted jokes and .. the internet.
I was going to mention i like your wheels, but now i'll mention your portfolio is of Yachts, and the bugatti logo? I would of assumed you'd use famous yacht design to inspire cars but what do i know - i'm a computer scientist, and i have no portfolio.
If you like auto design - you'll like this picture, lets be friends.
