Hi there i’m working on new model based on my own sketch here the latest update :
and i’m adding the additional shapes 
CC are my pleasure the sketch on comment
and two shots where i show in the first how i made the character with some plants to creat the depth and fill with the background
and the second where i show the 4 layers of fog i made with clouds image mixed with transparent shader + Glossy + translusent to give the depth after plants and character
