Here's some vids of my Luigi from a recent weekly, I'd like to get some critique if possible.

Just some general stuff.
Work on spot dodging less. Times you were punished for it.
-Against RUN Dmx: 4:10, 4:36
-Against Spire Fan: 2:40
Also roll less. Times you were punished for it.
-Against Run DMX: 3:44, 3:46, 5:13
-Against Spire Fan: 3:37
*Don't roll to your opponent ever. Especially when you're in the center of stage. Instead work to hit your opponent off stage and command space from the center. It's okay to roll through your opponent to get to the center of the stage though.
-Against Spire Fan: 7:08
Observe your opponent more and give yourself time to react. Don't commit to a plan early and lose time from being surprised when your plan doesn't work.
It's like rock, paper, scissors. Let your opponent throw out paper first and then you can react to it with scissors.
-Against Run DMX: 4:16 stay where you were Falco had limited options of where to land and would have landed more closely to where you were.
-Against Run DMX: 3:00 You wavedashed and full hopped nair after your opponent(Falco) had just rolled to the side and dropped off the platform. I saw what you were going for but it depended on the opponent staying there.
-Against Run DMX: 5:43 Falco fell too quickly for you to hit him with an up air.
-Against Spire Fan: 7:42 Follow up with an aerial instead of a smash.
Practicing your spacing:
-Against Run DMX: 4:03, 6:23,
-Against Spire Fan: 6:35,7:30
Don't approach with a tornado from far distances. It won't work most of the time. It's more surprising to do it at short distances and gives your opponent less time to react to it.
Keep at it. Your tornado recovery is good. I can tell you were a bit nervous but with more experience in matches you'll do better. Fight more people that are better than you so you can learn more.
Edit:
Keep in mind that the green missile(side b) gets more lag time the more you charge it. Use short bursts of it to move the stage if you are high up and off stage. It also increases the chance getting a misfire.
