Use dtilt more sparingly.. At one point Falco was about 215%. He should've been KOd by either Dtilt or Fsmash a lot sooner. Furthermore, dtilt is easily punished if wiffed, and if it does hit at earlier percentages, it diminishes the return of the knockback when you need it most.
I think you could have used missile spam a little more to bait the falco to shield or reflector, which would let you either grab or zair punish. You want falco off the stage because his recovery is easily gimped, and grabbing helps you do that. Also, Samus shouldn't be taking hits after the initial dthrow. With DI and nair, fair, or zair, she can stop any chains or followups.
Pretty good samus tho.. just work on KOing early. the falco slipped up at the end and you capitalized with the spike, which was good. Being aggressive off the edge like that when given the opportunity is important for samus's ko game.
thats all for now.. if you wanna ditto let me know :]
