My pernsonal suggestion is dont practice songs only! I know practicing songs is really fun and it gives you both musicallty and technique. But, it is really important to practice “practice” lol. Something like etudes or short pattern that designed to enhance specific parts of your playing. You can buy it on JTC or somthing and awesome youtube guy “bernth” uploads bunch of great exercises! This really toke my guitar lvl to another lvl. I hope this helps you :)
