I have been a woodworker for about 30 years. You are on the right track. When you learn enough of the basics you will be able to branch out and be able to develop your own style, if you like. There is also nothing wrong with copying other styles out there. I learned long ago that most things have been done well before you started.
I wouldn't worry about what makes your work yours. If you made it, it is yours. If you want to cut a plain box joint by hand, then cut it out yourself and who cares. That box joint will have beautiful imperfections that a tablesaw will not give.
Use what you have, have fun and learn! You are a person that can make something out of lesser items, that is what it is about.
Post some of your items, when you are ready. I have followed you to see your progress.
Cheers!
