Combine a tapered body, round porthole, and curved fins to draw a small rocket. One side seam and a gray edge accent suggest its rounded form.
Draw a tall rounded body that narrows into the pointed nose. Keep its center line upright and leave room below for the fins.
Attach the visible side fins and a short lower fin. Draw a circular porthole with a second line for its rim.
Add the nose seam, base band, a curved panel line, and a small window reflection. Place a few small rivet marks and light gray accents on the body and fins.
A small thing to tryKeep the fins broad and readable. Tiny mechanical details can wait until the main silhouette feels balanced.
