I've been a freelancer for a year and feel my skills haven't improved all that much. I currently don't have any complex projects in the pipeline so now I really want to work in a team with a company to learn more.

Based on what I have in my portfolio what position should/can I go for? If my portfolio isn't strong enough what do you suggest I do to improve it?
