It looks like you're already doing those things. I did notice that a lot of the projects on your landing page are not linked from the grid but are linked from other places on the site. I'm not sure that shines the best light on your design.

While some people fly to the top of the design business. Most people work their way towards it over a number of years. I think that enjoying dealing with clients and a willingness to let other people make changes to one's designs is typically an important skill.

Good luck.
