for your first song, this is "O k a y". there's alot that needs to be worked on but over time you'll learn.

most of the samples in this song are off beat which isn't good. you'd need to fit the samples to the bpm the song is in. i'm not sure which daw you used to make this song so i can't really tell you how to do that, but, i'm sure google could help quite a bit. in the future, you should start to stay clear of mainly using samples as using plugins generally lets you have more freedom with what you can create. keep in mind that experimentation is key, messing around in whatever plugin you wanna use to make basses (the plugin called Serum is the most popular one but you can also use a free alternative called Vital) is where i started off with making dubstep. aside from all of that, the rest of the song is quite empty. by empty, i mean that the only thing for most of the song is a drum loop, and dubstep bass samples.

onto smaller things: the first bass sample thingy kinda fades in and the wut samples are. an interesting choice of sample.

i don't really have much else to say so yeah that's it
