Fabulous that you reached target! Well done!
The weight you are at is not too high, what other people try or need to achieve should have no bearing on how you feel about yourself right now. A lot also has to do with your age too. Ive just hit target as well, but im 55 and having problems with saggy skin, so if i lose more then im going to have some real problems to deal with. At a younger age you wont have these problems to the same degree, so if you feel that you would look and feel better at a lower weight then go for it. On the other hand if you feel really good at the weight you are now, then why lose more?
I would really suggest that you try to maintain what you have achieved for now, and then come January maybe, decide then if you need to lose anymore. You may find maintaining harder than you think, so it would be good to try to do that for a few weeks before you try to lose anymore, if indeed you need to.
