Pls help me. I don’t understand what am I doing wrong.

My first try to make macarons. I’ve given them as a gift, to my female colleagues, on Women's Day and the beginning of spring. What do you think?🤗

It's an actual holiday. heh!

Today is my third times trying out crystal recipe. Everything still looking good. Full mac today but i still need to adjust my oven temp because it seem alittle hot in oven some are crack but still a good mac. When it too cold my macaron isnt as smooth.

My first try , all of them cracked. The second, and third, were hollow. What did i do wrong🥺 Pls help🫣
