What makes Gilmour tricky is not the notes but the nuances in his bends and vibrato. I read something somewhere or maybe saw a lesson where they described his playing as "the notes are always moving". Years ago when I learned the comfortably numb solos, I remember thinking "this would be a lot easier without all of these bends...eeek!". But the bends is what it's all about. It's been over 10 years and I still can't capture the true nature of those solos...but I keep trying. I think few players really can. It's deceptive because on the surface his solos are simple...yet they aren't.
That's amazing that you've been playing for little of a year and you've come this far. That's awesome!!
