Lack of fill is one of the things that distract the most from the upper eyelids. This is especially true when fat is removed from the lid during blepharoplasty. Even if you had no fat removed, since you liked the appearance with the swelling, I would suggest filling the lid with a filler like Restylane or Belotero. These tend to last quite a while in the eyelid but will resorb and can be reversed. If you like the result, when it has resorbed, I would then do fat grafting to the area. Make sure whomever you use is an expert injector.
