slavic latters and pronounciations

Hi guys, sorry I cannot speak in Russian, but I'm from Croatia. Though we speak Croatian(Slavic langauge) I doubt that someone could understand me everything. That's why I am going to write in English. If you prefer, I can rewrite it in Spanish or in German. Or in CroatianSo, I'm really interested in the phonetics. I'd like to know the correct manner to pronounce some letters in as many languages as possible. Of course, Slavic countries. Baltics incluided.Starting with the letter "L". East(Russia, Belrus, Ukraine). In Russian, the L is really closed and dark. I know that in Belrus you have some letter, it's similar to Y with hat and it's something like in Polish, right? What about Ukranian? Is it the same L as in Russian or different. Next, letter , is it the same in all countries or ??H in Ukraine, do you have some "normal" H or it's always the H from the stomach? West(Czech Rep., Slovakia, Poland)As well, I wanna hear something about L. I know that in Polish they have , but it's more like W in English. Czech/Slovak??After E, do you have to soften the last consonant just like after I. For example: hlavn ("hlav"). And after Y, in the same way as with I?South(Croatian, Slovenian, Serbian, Macedonian, Bulgarian)I know them most because they are near me (more or less)Thank you guys!
