How to draw a girl by the sea
Reference by Alina
The picture

The lesson
Outline the figure from behind
Hair mass, sweater, the long skirt — one soft contour.
Add the body construction
Head oval, spine line, shoulder and hip lines, the arm's axis.
Build the soft masses
Torso and sleeve volumes, the skirt's bell, the hand block.
Draw the hair and folds
Wind-blown strands, sweater cuffs, the skirt's pleats.
Commit the clean line
Erase the guides; add the waves, foam and shoreline.
Colour the hair first
Deep black strands — sweater, skirt and sea stay pencil.
Flat-colour the whole scene
Blue sky, teal sea, sand, cream sweater — one even tone each.
Render the sea finish
Rolling foam, deep water shadow, soft light on the sweater.
