ORIGINAL UNTESTED PRACTICE BRIEFS

GENERATION
A small original toy sailboat floats on a calm pale-blue pond. Cobalt hull, single upright mast, cream sail and coral pennant. Clear side view, complete boat, open water, soft overcast light, simple shore. No lettering or additional boats.

EDIT
Use the attached approved sailboat illustration as subject anchor. Change the distant background to a quiet green shoreline. Keep the cobalt hull, single mast, cream sail, coral pennant and side-view composition. Retain the complete boat and calm water. No lettering, another boat or new accessory.
