Creative Logo Refinement Needed

I already have a working logo, but it reads a bit too basic. I need a fresh set of quick alternatives—nothing radical, just smarter, more polished ideas that keep the exact color scheme intact. Above all, the new versions must project professionalism.

I’m especially interested in concepts that make clever use of negative space while staying true to the current theme. Two or three crisp variations are enough at this stage. Please supply each option as editable vector files (AI or SVG) plus a high-resolution PNG so I can compare them easily.

If you’re confident you can elevate the look without losing its essence, I’d love to see what you can do.
