Indeed, they do.
A few suggestions/thoughts:
You barely threw any eggs. Throw more of them. You don't necessarily have to throw them at Sonic, since he can run in and punish the lag; you can also throw them close to the ground and in Sonic's path, to make it harder for Sonic to punish you.
As I'm sure you realize, watch out for the grabs out of the DJ off of the ledge. There were a few times in the 2nd match where Sonic tried to grab you out of your DJ, before he actually did, which should have been a tip-off to really watch out for it. Off of the ledge, DJ-to-air-dodge would work, as would canceling your jump with egg toss or down-B to regrab the ledge. You also seem to be a big fan of the dair when you're coming back to the stage (it did work well a number of times). Make sure you don't get too predictable though, or you'll get punished, like in 5:10 of the 2nd match. This would be a bigger issue against the disjointed types, like Marth.
Both times that you were grabbed out of your jump, you used egg throw too soon; you're better off waiting until you get your momentum going back towards the stage before using up-B.
Watch your rolls. His dsmash hit you twice in the 2nd match when you rolled back towards him off the ground (1:04, 4:44).
You dsmashed a couple times in the 2nd match (0:40, 4:34) when Sonic was behind you. Try maybe ftilt instead, which has a lot less ending lag, or a reversed down-B. Both of them would hit much sooner.
I enjoyed the little mindgame it looks like you had at 3:53 in the 2nd match, where you threw 2 eggs of the edge to throw off his timing, and then DJ-faired him. You had a nice combo in the 3rd match (2:04) to start off his 2nd stock, where you gave him 32%, and some good pivot grabbing all around. And I really liked the kill you got at 3:12 in the 2nd match; you read him perfectly. Since I was expecting an up smash (which probably accomplishes the same thing), seeing an uair made me really happy for some reason. I guess seeing an uair connecting and launching the opponent is just really satisfying.
