No, it in no way means your design is boring. But this is a great instance of going back to our Digital Roots, if we may!
Flat Design is a Web Interface that is making a comeback after we drifted towards 3D illusionary images. Design elements like Glossy Buttons, shiny Verticals & gradients and unnecessary textures are now outdated. Now, user want to experience Minimalism. Clean Designs with crisp cuts and Defined Color themes are back, as validated by Windows 10 layout.
This Web Design provides more independence to work on Color themes, Highlight and experiment with Typography and basically work with many more elements.
