Lo que pasa es que la r en ingles se pronuncia como arqueando la lengua hacia atrás, en español debes tratar de decir la r tocando el paladar atrás de los dientes con la punta de la lengua, es decir la parte frontal del paladar.

well i think it's difficult to explain because "R" has different sounds in spanish , for example: "pero" ( but) has a soft sound and "perro" (dog) the letter R has a sharp sound. :P

Hi! when I was a child, my mom told me that I should copy the car´s sound when It speed up; Imagine a mustang "rrrrrrrrrrr" ;)
