One comet with a rounded rocky nucleus, short luminous coma and a broad sweeping tail, no star field. Practice structure, perspective and developed values in graphite.
Place the nucleus and overall tail curve.
Wrap the coma around the nucleus and extend broad tail bands.
Resolve the connected planes and overlaps, then build layered details and a full range of local values. Preserve clear paper highlights.
A small thing to tryKeep the tail bands flowing away from the nucleus together.
