Customisation of an existing design for vehicle stickers

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
