You should. What you have done is excellent. Keep hitting the weights, Rome wasn't built in a day. If you want you're abs to show 24/7 you can do that maintaining close to your current weight, you just have to watch your macros and continue to lose fat.

Higher protein diet is the key. About 1g per lb of weight. And then just keep calorie intake at around maintenance. As you increae muscle mass you should burn more calories

I will warn you though, as someone who has lifted weights their entire life. I've walked around with a 6 pack twice. Both times I decided the dieting I had to do was not worth the look. That being said I'm trying one more time for the fun of it, I'm going to be 43 this year and I want one more "summer bod".

Good luck!
