Karolina, I don't want you to feel bad about my comments, I think you are talented and this is important more than technique. I'll be watching what you are doing and so for the rason I'm checking you as my UF friend. Trzymaj sie dobrze. n.j
P.S I guess I have seen your nice portrait done by Mirek T, it means like you already have the good guy to guide you but if I may be a help I'll try my best anyway I'll keep the rights to comment.
Karolina, nicely captured spirit of the fall season, good reflection in water and foreground grasses. I'd be however concerned a bit with the washed out skies. Most of the time it would be considered a flaw unless it's a part of specific expression. There are a couple techniques to help. Pozdrowienia, n.j
