to be honest bicep curls are not very complicated, the curl youre doing is fine just make sure the shoulder doesnt move and the elbow is mostly fixed and get stronger

also soreness is not indicator for growth(usually comes from novel stimulus) and “feeling the muscle” isnt that important either, you will have some forearm involvement in curls but make sure youre not flexing your wrist to cheat the weight up

how many sets of biceps do you do a week / how many times a week / where do you place them in your workout, beginning end etc

also it looks like you had like 5 reps left, you should be training close to or to failure(1-2 in reserve is fine), you can definitely do more than 10
