If you're going to spam my wall, expect crit.
The drumbeat, whilst uninspiring was at least of your own construction. The kick however, needs to be eq'd properly with the bass (you call it an 808, I presume). At the moment it is distorting.
The lead...massively unoriginal. You could have at least chopped up the notes and placed them individually yourself to create your own melody, or, if you were going to use the sample as was, added other synths in to create something different.
