Its lacking a bit
From what I heard you've placed most of your focus on your lead.
Thats good, but at the same time you can't neglect the rest of the instruments.
One shots are a good way to beef up any song (just play a single note or sample)
For example taking your clap sample, and using full wet reverb, adds a airy effect.
Your kick lacks punch, its a good idea to throw some compression on it, and cut out the high frequencies, layer a short bass note under it will increase the feel.
For offbeat notes such as the bass you have now, using a low saw wave (around C4) with some attack will give a side chaining effect without the side chaining XD.
Double up your hand clap with a snare, cut both out of the low freq. range, and apply some compression.
Filling note gaps with other sounds is pretty nice technique.
D: Oh my... I went rantign... well I'm sure this was constructive...
There are many other things I could add but whew.... .x. I like your lead, beef up the song some more though =w=d
