I use the technique that you outline quite frequently to correct reverse keystoning issues.
I don't think this is the primary issue with this image. The problem, in my view, is that you are trying to make a shot work that simply has too many contraints. Your finished piece reminds me of so many "selfies" that one sees on the net; self portraits with a wide angle lens that distort the persons face significantly. Increasing sharpness, dodging and burning and other similar techniques might improve the technical issues with the image, but the basic compositional choices the person made are simply impossible to correct.
Your shooting constrictions, compositional choices (wanting to show two faces), equipment constraints, etc are going to leave you with a somewhat awkward representation of the building. Shooting with a PC lens or shooting from the second floor of a building across the street will help with the reverse keystone distortion, but shooting with an ultra-wide angle lens and shooting so that the one corner of the building is close to the lens is going to result in a bit of a funny looking image.
Here it becomes personal taste. So long as you are happy with the image; great! But be prepared with other viewers not sharing your view. Loosing up on some of the constraints (for example doing a straight on shot) and you are more likely to get a compelling image.
