Yes, French is very front of the mouth where English does sort of swallow their L's. With
Odile in French the tongue ends behind the front teeth with a tiny hint of smile-pullback on the lips whereas in English it ends behind the lower teeth on the floor of the mouth with a wide pullback grin. I try to cop out with 'it's delicate' because it's soooooooo hard to explain adequately in writing and a good audio file would probably clear it right up!
