I like your kitty art. Very nice. The best way to get real good at doily making is to use a size 14 hook and southmaid crochet cotton #10. I can tell you if you get through one medium sized doily with it you can do just about anything. In my opinion southmaid is the worst crochet cotton made. The size 14 hook will hurt a little. It's all about tension in crochet. If you crochet with yarn you will tend to have loose tension. Doilies need a tighter tension. I always use a size 11 hook and aunt lydias cause it's what I can afford. I know what I told you above is true because I made a doily that way and had thread tension issues. After I finished the doily it ended the problem. I was good to go after that. It took me a couple of months to make the doily but I did it. Sore hands and all. That was many years ago. 40 or so years ago. It's just a suggestion.
