I think you should keep the color scheme, but change the layout and everything to how you have it on the demo right now. The super curvy edges look aesthetically pleasing to look at. I also like the dropdown-esc layout as well. I personally like the dark theme because it does not really strain my eyes compared to a white/black theme. Although, more professional-looking sites do have the lighter themes, so idk, it's your site, so choose how you may want to design it.
