Bacteria, moss, stuff.
I went sailing for a week. My drawn boats do look better now, if I may say so myself. :D
Bits and pieces of plants, a heart, small hearts...seems this is a doodle, don't you think?
A house. There, I named the object that must not be named. :P
Two horsefish, both rather colorful.
I see a lake, some trees on the shore and orange-colored pebbles.
A green fish and a pink one.
If there is a spider living on the herbs on my window sill, that makes said window sill a biotope, I think. Or maybe I should be cleaning more often.
