I guess it depends on what you want to do though. If you're going to be playing at this level forever then it doesn't matter. You pull shot was good, but then it should be one of the easiest shots for you to play coming from the position you are in with your backlift.
If you want to improve though, then I wouldn't be limiting myself to lofted shots on the leg-side. I'd be working on a technique that allows me to play shots all around the ground, because the simple fact is that if you play at a higher level then it'll take about an over to work out which shots you can play and which you can't and you'll spend a lot of time (if you last a long time in the middle) waiting to play your favourite shots while the bowler bowls elsewhere.
I've played against young guys in the past who were incredibly strong in one area (i.e off the front foot), but really weak in others and they end up spending most of their time trying to play shots they can't play while waiting for the bowler to eventually bowl in an area they're strong in (if the bowler's any good).
The less limitations you have as a batsman the better in my opinion, and having practically the whole of the off-side as a weakness will make it tough if you go up to a higher level.
