Snuffy, you're correct, it was me who posted the critique of your landscape shots. as i mentioned in my post, my intent was not to be harsh, and certainly not insulting, but to offer ways to help you take better pictures. i apologize if you took in any other way.
as has been mentioned several times, photography, like any other art form, is very subjective, and people on Facebook - many of whom probably haven't a clue about how to take a good photo - may have entirely different opinions of what is "great" than people on this forum. and there are many other forums, including some i belong to, that are far more critical than this, where posting anything but the best images usually results in either no comment all, or someone tearing your work apart. as Shadow said, if you're going to post your work for all the world to see, you should expect that people will offer suggestions, and if you're thin-skinned and take offense when their comments are not as complimentary as you'd like, you'll find it hard to get an honest critique, and that will make it harder to learn and improve.
i've found that many people who comment on photos in online forums, or on Facebook for that matter, simply say, "great shot" no matter what they might actually think (especially if they're your friends), because they're afraid to hurt your feelings. well, sorry, but that ain't me. if i make a comment, i tell it like i see it. if the image really is a good shot, i say so. if the image needs help, i try to offer constructive criticism to help the photographer learn to make it better. i try to be diplomatic, but i can't control how my comments are received, and i long ago realized that if someone takes what i say the wrong way, that's their choice, and their problem. i understand it's hard to get subtle meanings from typewritten text online, but please understand that i, and others in this group, are never out to hurt or insult anyone. we do, however, want to help others learn and grow, and that sometimes means being critical of their work and offering ways to make it better.
as for being "the only amateur in here", trust me, you're not, not by a long shot! there are photographers of all ages and experience levels here. i'm certainly not a professional, but i have been involved in photography for well over 25 years. i've had my work published, and have made a bit of money at it here and there, and i probably know just enough to be dangerous. i've also been posting and reading in online forums for 6 years or so, and i've learned that most of the time, when other photographers offer advice, there's some nugget there that i can benefit from. i can tell by the quality of their work whether or not they're qualified to judge mine; if i feel that they are, i take their advice, try it, and if it works, great! if i don't feel their comments are useful, i simply ignore them.
i hope maybe this has cleared the air a bit, and i hope you will post more of your images. don't stop practicing, and don't stop learning. don't take offense at others' advice on things like lighting, composition, etc., take it for what it is - a suggestion on how you might improve your work. if you like the results, great, keep doing it. if you don't, feel free to ignore the suggestions and move on. it's that simple.
