While I appreciate you trying to make something unique by combining two midis - Just dropping sounds into garage band and changing how things sound doesn't really classify as a remix.
You need to add your own beats - get rid of that drum track. You need to pick better sounds and work on the arrangement. just throwing sounds around. 1:36 is audio hell. It's just blips and boops and sounds really chaotic.
Really this feel like a D-, you put some effort into it but it's obvious you kinda phoned this one in.
