The jump up sounds cool mate, but things are missing. The last bars right before the drop sounds too easy for me, add some more FX sounds to build some tension.
Also I think your drums are too flat, get some more movement and energy in there, I like the videogame sound though!
For the techy tune, great intro. The snare could be a little fatter.
The basses sound cool, but they lack sub frequencies, so work on that, layer a low sine wave underneath!
