First try !

I'm not a fan of macarons, if I go somewhere and find them I will try one just to confirm I'm still not a fan, but I recently got a thermometer and got obsessed with trying macarons for their technique.
I did a lot of research about "croutage", "macronage" and whatever and ended up trying the recipe from the famous Pierre Hermé. I went for a chocolate version cause I didn't want to use a food dye and a chocolate filling.
They're not the best looking obviously but they taste fine for a first try.
I'm planning on trying again soon and taking them to my colleagues for a taste test.
What do you think went wrong ?
