First of all... well done you! That's an impressive amount of weight you've managed to lose. Seriously, even if you don't quite look how you would like, losing the weight is so worth it just to feel fit and have so much more energy to get out there and do the things you want to do.
I just wanted to say that assuming you've only recently lost the weight, what you're seeing now is probably not the final result. It's quite possible for the skin to shrink down a fair bit, probably not as tight and smooth as you would like it, but definitely to an acceptable level where nothing would look too out of place.
Keep doing those exercises, toned stomach muscles are a real plus as far as your health goes, no matter what covers them!
All the best
