Sounds good to me.
You've obviously been listening the Grados long enough to train your ears to them. Those cans are notoriously bright and lack bottom, which tends to result in muddy, boomy mixes. But this piece exhibits a well-balanced spectrum to my ear.
It's perhaps a little quieter at the lower and upper extremes than what's typical for the genre, but then I find most contemporary electronic music annoyingly overstated under 60 Hz and over 8KHz. For my grumpy old ears at least, you've found the sweet spot.
