Customisation of an existing design for vehicle stickers

Description

For a customer's vehicle, we require the attached graphic to be adapted as follows:- All elements in the sky except the sun are to be removed- Sea and beach should be larger and run further to the right- Mountains a little lower and more forest- Remove caravan and fire. No more vehicles should be visible. Fill the graphic with forest instead- Trees and palm trees should be more delicate and not completely filled in. Only work with outlines and shadows!
The site of the sticker is the following: 250 cm x 100 cm
