Hi Mani,
Welcome to the boards! I think this portfolio needs a bit of work in showing what your point of view and who you are as a person and a designer. Your portfolio should tell a story while of course showcasing you work. At the moment it show the viewer a lot of renderings with no meaning behind them. I would like you to ask yourself what kind of job do you see yourself in? Then what story do you need to tell to get that job? If it is a toy job you should be showing character development skills both in sketch format and renderings, along with and understanding of toy trends, manufacturing and processes.
I would also drop the automotive work. It is really weak and is not doing you any good. Automotive is a subject that you either do well or you don’t. It looks bad if you don’t know what you are doing and brings all of your work down.
Hope this helps.
