Mcflubbin - Game Remixes (Halo - Zelda) & 1 Origional

[Mcflubbin]

Hey guys,
I'm fairly new to dubstep and I'm really wanting to improve the music I'm producing. I have a lot of fun making music and would love to be able to further my skills in it.
I am open to all criticism. Also, sorry for doing so many at a time. I figured this would be the most efficient way.

This is my favorite remix I've done. Halo was one of my favorite games.

This is the first dubstep song I attempted to make. Strangely it's one of my best.

My friend asked me to make a Song of Storms remix from Zelda. This is it.

And finally, after making the first song of storms remix, I was a little dissatisfied. So, I re-created another one from scratch. Still a little disappointed by it though,

Please let me know what you think.
