Salut! 
I have recently begun learning French - and I enjoy it so much! I study phonetics and grammatics in paralel, and, to say honestly, grammar is much easier than pronunciation. My biggest trouble is "R" - I cannot catch that soft palate vibrations like when you gargle your throat with water (friend of mine suggested me to try this approach - she said it was helpful). Mine R sounds more "gh" than "r" :( 
Any tips from natives or learners faced the same trouble? Can you describe how you pronounce it? Maybe, there are videos or turtorials on pronunciation you can advice. I would really appreciate any aid!
