4.5 pure
This is entirely deeppaint apart from the snail which is a sphere that has been sculpted (this is my first sculpting trial)
The shell is deeppaint over a sphere then turned into a line mesh. the Array modifier created the repeating growth of the shell. the final shell shape was tweaked, scultpted and then vertex painted
The landscape is a simple grid mesh sculpted and painted. with all other details like vegetation being deeppaint and further sculpted and painted
