The drums could be more professional, the samples are a bit cheap. The arp is cool but a bit random and very loud. There's too many transition crashes imo and they are very loud. To avoid loudness war I can recommend you to sidechain your instruments to the kick/snare, the sound will be way neater. You can better drums samples at cymatics.fm. Presets are good but I don't recommend you to use stock ones, they will probably suck most of the time. The e-guitar you used in the last part as well is very loud.
Keep it up lad!
