Nice videos.
You're good. But I do have some critiques.
On the first video, it was very repetitive. The entire song sounded the same. Try modulating some phrases. Mix it up!
You're rapping is almost grade A. I would recommend you sound angrier when you record. Seriously, belt out those words with anger or some high emotion, because as of right now, it sounds like your spewing out some rhymes. And don't get me wrong, the flow is nice, but it's not energetic enough.
