Moved to an appropriate gallery forum; "Beginners" is for questions, not critique. With respect to the images, How about you telling us what your thought process was? Why that image, from that angle at that exposure?
Hi Aivariukas and thanks for sharing your work. I have two suggestions:
(1) Get closer (photos 1, 2, 3, 4)
(2) Have a focal point of interest (photo 4)
