Hey, I'm 66 and I'm still learning. I have quilted on and off since the mid 80's but I am not nearly as good as most quilters on this board. But I still make pretty quilts and enjoy doing it. I usually do scrap quilts and use easy patterns. My creativity comes with choosing the 'scraps', layout, etc. I have done applique and more complicated patterns, but prefer scrappy. Just do what feels good to you and enjoy what you are doing.
Your quilts look great.
