Rurik, excellent!!
How you make the shading?
With which program? Gimp?
I'll try to explain (sorry for the language).
All the paint in the Paint
1. Use ready-made images with a shadow. As the workpiece.
2. Cut and paste .... and that's all
.......
300 years to cut and water the grass. And you get beautiful English lawn ....A very simple secret.....
