Nét Vẽ Quái Vật Trên Ứng Dụng Vẽ Tối

A clean screenshot of a dark digital sketch tool interface displaying a deliberately crude doodle in progress. The canvas is a rounded [dark charcoal] drawing panel filling most of the 4:3 frame, set over a subtly dimmed app background. In the center, a rough [white] line-art monster is drawn with thick, uneven brush strokes: a hunched fantasy creature with a long beak facing left, a jagged open mouth, a scribbled oval eye, a high arched back, bent legs, and a long curved tail. In the lower left, a small [teal] flower doodle on a stem faces the creature; in the upper right corner, an [orange] sketch of sun rays radiates outward. Interface layout includes: a top-left close "X" button; a floating top-center rounded toolbar containing six icons (pointer arrow, squiggly brush, text "T", shape duplicate, eraser diamond); top-right undo and redo arrows; a vertical brush-size slider on the left with a single circular white handle; a bottom horizontal palette of 16 round color swatches with the yellow-orange swatch selected by a blue ring; and a vibrant green circular checkmark confirmation button at the bottom right. Minimalist, playful dark UI aesthetic with intentionally messy, casual digital drawing lines.
