| Honestly, dont worry about that man. You're not playing classical guitar, your form can only get you so far, but if you choke the bass like you said, it will lead to really bad habits and will cause exhaustion. Generally, I find a lot of shredders and technical players to slide their thumb so that its aiming towards the headstock anyways. The only reason people put emphasis on your thumb pointing toward the ceiling is because some people make a habit of keeping their wrist bent while playing, and can potentially hyperextend their ligaments overtime. On the same note, some people play their entire career like this and will suffer no injury. So yea, you've got the right idea playing with good form, but playing whats comfortable is really whats more important.
