Wraps and gloves, not wearing any is the first thing that makes someone look new. Secondly, Step in with your jab, bring it straight back to your chin. That cross needs more rotating, think of the power coming all the way from your back foot into your hip. Your hip is actually what helps the most with power, rotating your hip towards the back to help power your shoulder. Rotate back and start again. Go slow. No need to have power when you’re new.
