Hm, I love present tense. The 1st person present tense. It has a sense of urgency, makes everything sharper, as if you are an immediate participant of the events.
It is a pleasure to read and could be very enjoyable to write in. It's like a fevered dream.
Past tense is safe, but it is apt? You need to think about it more, most importantly – why are you doing this. I like weird POVs, 1st person unreliable, for instance. But am I being perverse? And why? What is my goal, my reason? Try different POVs and you will know immediately what speaks to you. You don’t write a novel for a reaction. You write it for very personal reasons.
