I'd say you've come a very long way in a single profile and the end result looks great. Profiles tend to get to a point where you get sick of looking at them and/or you cant see the wood for the trees. So at this stage you think you've done enough . . . but if you come back to this project in the future, I'm quite sure you will have learned newer skills and with a fresh set of eyes, instantly see where you could push things even further.
As it stands, its a great profile that captures the original quite well, well done.
