@shiftitamanna, good explanation about the meaning of naturalism, I have seen some documentaries where people go into the forests and jungles to observe the apes or other animals in their natural habitat.
Looking at your drawing, I think that at some point you have practiced diving since you know marine plants and algae very well.

Your drawing of marine nature was very beautiful on you, in addition to the variety of algae and plants they have beautiful details, the drawing is very beautiful and colorful. congratulations

I say goodbye wishing you have a happy day
