Wow, thanks for sharing pictures as I also ordered the 38mm - it looks good on you, hopefully not too small? I figured that because the Apple Watch is rather bulky, to get the smaller one might make it more manageable.
Yes, I have tiny wrists so it was always the 38mm for me. It's not too small, no.
Just trying to find the correct watch face at the minute and I think I've found it; the Modular in blue!
