Yes. Exactly. It's a forum that pays a big attention of the photography, but it's not some professional photography forum. So, we're glad to see all kind of photographs -- professional, semi-professional and I even upload some of our blurry photos (it's not a collection, just some in the related threads).
I think these photographs are good enough. They're clear and I think the colors are pretty real/natural. What more we need?
I'm almost sure that the the 4-th plant is common here in some fields and gardens, parks...
I'm not good at botany (but I like this science). So, I just may guess: on the 1-st photograph I see a leaf of
geranium (

lucerne(aka
alfalfa) (

You know what? If I'm a billionaire and I have some good passive incomes (like I buy some garages and I rent them to people to make shops, restaurants, offices, etc.), then I'll have a lot of free time to spend on purely intellectual activities. And one of this activity should be to learn the names of as many as possible plants and to enlarge my music culture.
