Well, one of the things I noticed first is you abuse forward smash bigtime. Sometimes your opponent wouldn't even be near you and you'd start charging up forward smash. For one, it's just unnecessary. Two, it gives your opponent time to think about what he's going to do next. Three, if your opponent is a character exceptionally good with SH, he will SH in your face or use range right after you swing your bat and **** you up. The fourth thing is you're destroying the power of your bat because of the diminishing return effect. If you use one move over and over, it will gradually get weaker with each swing. This isn't something you want, especially since fsmash is a finisher. What you need to do instead is learn to tilt attack more, along with some other moves--because I don't think I ever saw you dsmash, dair, or bair. That's not including ground tilt moves, either.
Your opponents look like they shield abuse. The way to punish shield abuse is to stick on them and never let them breathe. I don't know about you, but as a brawl player I went into the game almost never using shield. Now I do use shield, but I use it at just the right times. People who like to abuse shield are stupid, but Lucas is perfect for punishing that kind of stuff because of his tilt arsenal among everything else. Don't let shield abusers breathe, Lucas has the power to make this possible.
I see you have SH down pretty well, but you only used it for PKF. SH fair and SH bair are both very strong moves, you should use them more. Your game is very ground-oriented and focused on Lucas's ranged attacks. You need to switch it up a bit, because I felt you always gave your opponent so much space when you resorted to PKF's and freezes. Maybe this works for you though, but in any case when they get near you, you need to have more variety with your melee attacks.
