How to move past move the "clean and correct" plateau?
Hey everyone. I'm a freelance designer (mostly doing posters for clients). I have already attended the "design bootcamp" suggested by this sub and I believe I know my fundamentals well. (e.g. using grid systems, hierarchy, colors, and grouping). My designs work (in the sense that they communicate the concept clearly and are accepted by my clients); however, I have noticed that they feel blunt, soulless and too simple.
I would like to know if this is a common experience for beginner designers and how to push past this. How do you get that high-end, sophisticated feel? Are there specific resources that could help me cross this gap?
