People who clown your attempt usually aren’t attempting anything. Their seat is in the bleachers.

Mockery is usually cheaper than participation, and it tends to come from the people paying the lowest price. Someone in the middle of their own difficult thing rarely has energy left to sneer at yours. The commentary says more about where the commenter is standing than about the quality of your work.

Notice who is talking and check what they are building. If the answer is nothing, weight their opinion accordingly. Save your attention for criticism from people who have made something and know what it cost, because that is the kind that can improve you.
