I'm not a dressmaker, I'm a quilter
Looking at your blouses, there's no reason for you not to be both. Now that you have altered your pattern to suit your requirements it can be called a TNT (tried and true) and you can use it to make variations of that first garment.
If you are interested in making yourself more garments you might like to read Carolyn's blog http://sewingfantaticdiary.blogspot.com.au/
I've learned a lot from Carolyn as she describes her processes and procedures so well.
Best wishes for both your quilting and your dressmaking adventures.
