From what I can see, you can certainly do a stache, soul patch and goatee and these will not be connected but would look very nice. Also some long side burns. BUT, it is really hard to tell after only 3 days. You need to grow longer, weeks of months, and then decide what you will keep, which will likely be what I just stated above.

Now as far as minoxidil goes, I have never used it and do not have good advice for that. See what a dermatologist might think of where to apply and how much, how often etc. Some of the guys here may have some advice for you regarding this.

For now, grow what you can. You are still young and more beard maturity is likely in your future.
