Alex, I think you’ve gotten some great feedback based on the previous replies.
One thing that I might add is that you do not need to show the entire process for every project, but you should try to illustrate that process on at least one or two projects, your favorites. Let’s face it, not every project is going to have this amazing back-story, and not every project gave you the chance to develop thorough research and form development. Pick your favorite projects and try to elaborate more than you are currently.
This may be just me, but I like to see a wide range of form development sketches for at least one or two projects. I want to see that an individual can develop a range of compelling designs, not just come up with one design that they “like” and quickly finalize it. The “hub” and “bottle top” start to show a small range of sketch options, but they seem pretty brief and only seem to be scratching the surface on options.
I would agree that on first glance, it is a very nice portfolio. It has a clean layout, and the imagery and renderings pop. Beyond that, I start looking at content. Can this individual design at a level I want to see, or is a nice graphic layout and renderings overshadowing his ability to design?
