Your quality of work, presentation, ideas and execution of projects are all excellent.
I’d agree more sketches and process would certainly help, but that being said, you’ve got a lot more showing that just final renderings, so personally I get a pretty good idea of how you think and what you could achieve if I threw a project at you.
Your work itself shows good diversity and the presentation is of reasonable depth and breadth. I was able to skim your site in a few minutes and come away very impressed with a solid idea of what I think you are capable of.
Do you have a more in-depth portfolio or project specific document you follow-up with? If I was hiring, I would certainly like to get a little more in-depth with your process and some of the nitty gritty problem solving following the first round of portfolio review.
Keep at it. Good work will get you far!
