First of all welcome and great job so far,
Second, everything ScottR said.
Third, a right angle grinder and flap sander makes a wonderful carving tool, esp. for wood like this.
Fourth, while ScottR is right, good to use inexpensive woods for learning - you are also right in that there are better woods for working, and with the labor involved you may want something more like mahogany or ash.
That said, ScottR is also right again in that pine can sound amazing. I've made prototype bodies out of glued up 2x4s, just to get a feel for the shape and carve of a body, When I hacked out a neck pocket and string it up, it had an very chimy, bell-like tone that was pretty stunning.
