Ok, first of all, nice choice in color
. I haven't played enough to get too match-up specific, but I can tell you some stuff with fundamentals.
What I know about shulk is that shield form makes it really hard to recover. If he uses it off stage, just go off and fair him. Almost the same thing with smash form. He takes more knock back, so just kill him if he's trying to recover in that form. If he has smash form on stage, it's much easier to just avoid him until it runs out.
You're movement is pretty good, but you full hop too much. Practice short hop fast falling aerials. Doing that makes it harder to punish sheik, and sometimes you can cover your landings by jabbing/grabbing when you land. Don't get greedy with combos. Know how much damage you can inflict before they can retaliate, then back off, see what they do, then punish. To me, it looks like you're throwing moves out everywhere, making it easy for shulk to counter. Sometimes it's just better to wave moves in front of your opponent (without actually hitting them) so they either wiff an attack, run into it, or do something punishable (like counter). Grenades are pretty good, but don't be afraid to get off stage and go for a gimp. Also, you're not respecting shulk's range. You got hit with wwaaaayyyy too many random forward smashes.
Other than that, you seem to have a lot of your tech down. Just practice awareness and spacing.
Pro Tip: sheik's up smash can tipper opponents on battle field's side platforms when she is underneath. Didn't see you do that those matches

Gonna do this on the same post because double posting is still bad i thing i think....
Anyways, look at my third paragraph. Most of that is relevant to you. Learn what are true combos and what isn't. Work on your approach game, because rolling into your opponent every time you get close to them is going to royally screw you against a lot of players. This could be either spaced tilts, spaced aerials, or just dashing/jumping around in front of them until you see an opening. Use sheik's speed to your advantage. If your opponent is walling you out too hard, then back up, pull out your needles, and give them hell. And if you hit them with your needles, that gives you a chance to get close since they'll be knocked into the air. For stages, I couldn't tell you much right now. Haven't messed around with too many of the counter picks. Basically just choose a stage that you feel comfortable on. Bonus points if the stage hinders your opponent or gives you an advantage. For example, if your opponent's main kill options are vertical kill moves, choose a stage with a high ceiling. If your opponent has low mobility or no projectiles, choose a long/flat stage like FD and force them to approach with needles.
