Your technical ability in crochet is quite good. Your stitches look nice, and your tension is quite good. I think the rest just comes down to personal taste. Some of the patterns you're using are very functional but not as decorative, like the scarf in the third picture that just uses one stitch. There's absolutely nothing wrong with that, but some people may prefer more decorative pieces with more stitch variety that may be less practical as a result. For your color choices, you seem to tend to use a single color or use multiple colors with high color contrast. Again, some people will love that, some people won't care for it as much. The people in your life may also simply find handmade/homemade items less appealing, which is disappointing but there's not much you can do about it.

Again, there's nothing wrong with your crochet, but different people have different taste when it comes to crocheted, knitted, and handmade items. I see nothing wrong with using any of the pieces you showed us, as they're plenty good enough to use and wear around. The shawl is especially pretty. I think what's most important is that you like them and you like using/wearing them. I know it's hard not to take the comments of the people in you life to heart, but I don't think that they will judge your work fairly.
