Not bad, I like the intro. The pluck and melody is good, although it does feel slightly thin, like the layers could be more full and background stuff could be added like a soft reece bass or some pads. Buildup is also quite energetic, albeit a little sudden.
Not sure about the drop though honestly. It's heavy, impactful, and I can hear the idea, but it's just really short and doesn't fit with the intro. Mixing isn't bad, but the synths are a bit dry and overblown texture wise. Drums are punchy, but the snare does get buried a bit by the synth
so yeah, some good here, I like your melodies and ideas, you have the basics of brostep, but I would work on mixing, layering, and expanding sections to feel more natural along side each other transition wise
