A mystical holographic illustration featuring three medical-themed Halloween characters in different poses. A black cat doctor wearing scrubs and a head mirror, sitting upright with a serious expression and glowing cyan eyes. A ghost nurse floating with arms outstretched, draped in flowing holographic medical coat with a tiny medical bag floating nearby. A mummy cat standing on hind legs wrapped in pristine white bandages, holding a small syringe with rainbow holographic effects. All characters feature the same iridescent rainbow holographic sheen with deep black silhouettes for the cats and translucent white for the ghost. Spider web backdrop adorned with floating stethoscopes and thermometers instead of traditional Halloween elements. The holographic rainbow effect creates prismatic color shifts across purples, teals, blues, and golds on all medical accessories and costume elements. Moody purple gradient background with subtle sparkle effects and floating medical crosses. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
