Hi Erna I am not at a stage where I can give you any technical critique, so no advice but, I like that the tone of your photos are different; the first one has a delicate quality and the last one is quite dramatic. My favourite is the middle one which has a nice palette of colours.
Truthfully, the only one that says "SPRING" to me is the middle one. The first one's editing style is too cold and gloomy for a happy spring shot. The third shot doesn't seem 'springish' to me b/c the trees in the image are around all year long, not particularly a only spring/only winter type tree.
