Brandon you got a set of balls and good chin mate you push the action but that is your style,you have zero jab and come forward very square shouldered so you present as a target that easier to hit at the moment due to your wade in footwork.
I think you did better in the first fight, they are only three rounders but because of it they are flat out, if you really improve your cardio you will finish as strong as you start them, that could win you fights like the second one. Your arms were out there but you were tired. If you are going to be that type of fighter who wades in squared up you are going to have to work on uppercuts, hooks backed by great inner footwork and be able to throw in front of the oppositions shots and spoil their timing as they move. Work on fitness cardio and flexibility in legs and waist,work on moving on angels when you are slugging it out like you do instead of just trying to outwork them in there.
Most of all work on not being so committed and square in every range. When at a distance use your jab and your timing off it and use it as control and when to gauge the time to move in and off of the lead jab while parrying with the rear hand. Your lead shoulder will protect your head more in that one leg forward style and its only a slight twist to be back into your prefered squared up (if thats how you wish to fight) on the inside (where you can get away with it more) If you like to fight square and use both hands equally you need to learn angels and how to get around to their flanks when in close so that you got two hands verses their one and catch them turning as they adjust to you. Go to the body too when you get used to ducking and twisting in close it will suit you, work on your hooks and upper cuts in there with your feet adjusting behind your angles for power.
