For shitty equipment you did a hell of a good job. Extreme Death Meal to the core! However, if you would like a better head start on your musical work, then I would recommend you get a TASCAM US-144 Interface. With a TM-78 condenser mic it comes to around $300 Canadian, best thing I ever bought to get my music career into gear.
Other than that, you got a good thing going, don't give it up!
