You're far off if you're going for a traditional rock mix. However, the mix style you've got here works fine. I would tame a few things so your 1.5 - 2.5Khz region isn't so sharp, and you've also got your drums making some nasty peaks at around 8-10Khz. Shoegaze typically is a lot longer than a minute and a half, and if you really want to drag it out, you can extend pretty much every section in here quite a bit; let it draw out.
