Achilles95,
Even the top pros in Western Boxing, Muay Thai, etc. lost fights somewhere along the line.
It sounds like you've done some pretty good self-assessment, in terms of what you did wrong.
Learning to relax, when you're in there with someone that's trying to take you out, only comes with more experience. Maybe tougher sparring sessions leading to your next fight would help in that regard, depending on what your trainer thinks. Getting that first bout under your belt, may also play a part, in being more relaxed in the ring.
Shadowboxing with light weights, or 16 oz. + gloves, while watching yourself in a mirror, might be helpful in keeping your hands up more, as will being mindful of it in sparring. Your footwork will develop as you train longer.
If fighting is in your blood, and you want to continue competing, don't get down on yourself, and work hard on those weak areas you've already identified. Good training, and good luck, my friend!
