Good pop in ur job. Ur left hand u want it closer to your chin also. I see ur tryna bob and weave but its all good for a beginner, but aye u lean ur head to much to ur right when jabbing, and as mentioned earlier by another poster, a left hook would have u staring at the cieling
You need to mix ur punches up also. All your doing their is throwing loads of jabs and then maybe a cross. U need to throw some "body" shots, work on both the head and body. Try coming close to the bag as though u fighting on the inside and throw some combos.
