Agree with Tiffany. In spite of the tilt, it looks like a happy, healthy plant. I would let it acclimate to its new home for several months before trimming. Place it so it leans away from its primary light source...that won't balance it out but it will prevent the tilt from getting worse. You also could try staking that main, leaning stem upright more aggressively and straighten it a bit more every couple of weeks. I can see why you might want to correct the lopsidedness, but it's actually quite graceful and attractive as is. Sometime in the future (not soon, let it settle in) it deserves a more attractive, possibly shallower, pot that accentuates its structure.
