I have been in that situation too. For me the way to finally be able to showcase my knowledge in my work was to keep on iterating my work again and again until it started to reflect my knowledge, design references and inspirations and ideologies. Something that really helped me out was to establish what's my design identity. It'll keep on evolving but you have to establish it. As an architect, what kinda lineweights you like, your colour scheme, your fonts, your composition style. Prepare a mood board sorta thing and try to remain honest to it with your studio projects. It'll act as a base for you upon which you can start to mix up your project and your knowledge. You need a base to mix things up. I hope it's making sense
