ahh, nice to be starting :)
i'll try to give you a lot of feedback so that you could improve :) sooooo where to start.
the main problem that i would have you focus on is that the track doesnt change very much and doesnt have a lot of depth. as noted earlier there is only one kick and a sawtooth melody playing, so not a lot is really happening. the melody itself, however, seems to be moving fairly interesting because it doesnt flow on a regular meter--it doesnt seem to just repeat every 16 beats, so it flows interestingly and actually is fairly listenable.
what you would want to do is a few things. first, make the drums more interesting. instead of just a bass drum, add in other forms of percussion, like high hats, snaps, chopped up sounds, sounds of metal and junk and stuff, congo drums, hell, whatever you want, so long as it stays in a coherent beat. make it move, make it interesting and make it fill the silence [unless silence is what you want].
play around with the synth sounds you are using. add in a bass synth--to do that, make a sound and play low notes. it would really fatten the song. tweak the sounds you use. throw in pads and effects to make an atmosphere. but whatever you do, keep it simple enough that your song doesnt become a sonic mess--try to limit the number of instruments playing at one time to prevent that from happening.
and the most important part--vary it. lose the bass drum at points, change up the melody and way your synths sound. make interesting transitions.
i hope im helping you out as a beginner :) good luck!
