First of: great selection of music and some sweet fx. That part is solid.
Something to think of is that your soundlevels get a wee bit low when you mix from one song to the other. Let them ride together for a while longer. That way they add more to the mix. If one song has too short of an intro then loop it and bring it in at a low level, work it in.
You really got something going. Just try to keep the levels up a bit. Big like on the outdoors setup, btw what gear is that?
