These are nice images, Ossi. If I may offer a point to consider regarding the "rotten fungi" image...
You always want to be cognizant of shape and pattern. The human brain, when confronted with an unfamiliar image, immediately tries to find familiarity by looking first for familiar shapes and patterns. In the case of this image, it first screamed "Smiley Face Mushroom" to me. Taking at least one of the leaves off of the large cap would have prevented that.
Remember, as the famed artist and color theorist Josef Albers stated, "Shape always trumps color".
Nice work. I'd be very eager to see you take another swing at this "Autumn in Finland" theme by showing another image or two that really are rather unique to your climate, culture, and natural environment at this time of the year.
