Great work! Few advices tho, to avoid long term issues with your fretting hand, keep that thumb on the back of the neck and do a circular motion with your wrists for the bends instead of pushing upwards!
actually that hand position is ok when bending to allow for vibrato and for strength, but when you do fast runs or stretch very far then its good to keep the thumb behind the neck
same thing the other guy says, also id bet brian may does that with his hand because 1) it looks cooler on stage and 2) he was always a more bend-y player from what i remember
try to play with ur thumb behind the neck, trust me u will play more faster and efficiently. as a person who used to play with his thumb like that, take this advice :) solid playing btw
