From a production sound point, you drums seem a bit thin, and too prominent. Less concentration on the snare and high-hat, more on bass and cymbals, especially for your type of music.
Guitars are lacking a lot of tone; they sound distant and artificial. Try toying around with your pedals/pre-amp/computer effects that you may be using.
Slap bass sounds good

. Needs moar.
It's not my cup of tea, but if you were to just make a few changes, your sound would improve a lot.
Keep it up.
