Orite m8,

i looked at your first video and noticed that you were throwing your hands about when you had stop punching, get them straight back to the side of your face ready to defend.

on the second video you change that your hands are right back to your face after evrey shot, also your hands are looking prety nippy, just get on them toes and move around abit more, take it easy at first and when you feel more comfortable start to move as the bag swings in and out (follow it)

not bad though m8 keep it up,

im only 16 myself so i cant help you as much as the other people on here but i hope you take it in

cheers
