Put combos on the bottom of the priority list. There's no reason to focus on combos when you can't land a proper hit against a decent player. I'm not sure how Netherrealm games work, but understanding your character's move-set and learning how to punish common moves/strings should be a good starting point.
This is definitely one of the best advice if you want to improve tremendously. I used to try to blame everything but myself for losing and I rarely improved for a long period of time. After I got tired of losing to what I thought were scrub tactics, I went to training mode and figured out how to beat most of the moves that led to my losses. Fast forward 2 months later, I became significantly better.
Rule number 1 for fighters is that it's ALWAYS your fault when you lose, don't look for excuses figure out what you are doing wrong and try to experiment with different options vs said things that beat you. Your initial goal isn't winning, it's figuring out the tools and tricks you need to do to win.
