Pushing boundaries (Feeling lost and helpless within the canvas)

I'm going 40x30in. I'm getting tried of painting small. There's something about small paintings that feel extremely intimate and comforting —almost nostalgic. I want to achieve the exact opposite effect. I want to feel like I'm stranded in the ocean with no visible land around. I want to see the painting and feel isolated, engulfed and inconsequential to its presence. 40x30 does not achieve that yet... but it's about as large as my studio will allow. Should I make a life change and move somewhere new? I think I might.
