no problem. I think we can often dissuade ourselves from going for things, but as the saying goes, you have to be in the right place at the right time... so be in that place. You have to reach out for it. Remember, a portfolio is a living thing. I've been hiring designers for about 10 years now and I've seen portfolios from some of the same people for that entire time. They evolve, they grow, and they stick in my mind. The fact that I have seen them improve over the years is super important. My own portfolio isn't done... it never will be... it's ok, it is just representation of a point in time.
If you have any doubts, or want to get a quick feel for what is working, don't forget to post in the projects or portfolios forums.
