Abstract Acrylic Art on Mirror

I have a medium-sized mirror (roughly 12–24 inches on its longest side) and want a bold, abstract acrylic composition applied to just part of the glass, leaving the remaining area reflective and usable. The paint must adhere cleanly to glass, sit flat without obvious brush ridges, and be sealed so it resists chipping or moisture. I will provide a photo of the mirror, reference colours, and the exact section I’d like covered once we start. Your final deliverable is the fully cured, sealed mirror ready to hang.
