专业角色参考图布局

Create a professional character reference sheet for the uploaded image. Arrange into {argument name="column count" default="four"} vertical columns, each representing a viewing angle. Each column contains a full-body view above and a matching close-up portrait below. Columns (left to right): Column 1: Front view (full body above, front portrait below); Column 2: Left side view (full body facing left) with left portrait below; Column 3: Right side view (full body facing right) with right portrait below; Column 4: Back view with matching portrait below. Maintain even spacing and framing around character portraits. Clear outlines, consistent alignment, and clean panel separation. No text. Thin borders. Flat lighting.
