Thank you very much Slobodan, Rob, Ron and Russ for your comments.
@ Slobodan: I have print all the images in 20x30 cm format (more or less, on A4 paper with a white margin) using my Epson R2880, but I'll eventually print some of them on A3 or A3+ paper.
@ Ron: I shots many times that tree (the one in the second image), I find it every year a more interesting subject.
@ Russ: I cut the left side of the building to add some "tension" in contrast with the free space on the right side, between the old house and the forest.
(...I hope that my English is clear and correct enough...)
