Should i make this mine?

I have a small wrist at 5.9 inches. But I wear big watches and that’s suit me perfectly. An aventurine dial as is yours

after a week of wearing its not going to seem big. I used to obsess about this - I have 17cm wrists. It used to stop me wearing some watches. Convinced myself my SMP 300 was too big after wearing my 16710 for a few weeks, and very nearly went Speedy reduced when buying first speedmaster (I changed my mind before buying). I sometimes wear a Garmin smart watch, that I think is 46mm and I wear my Tudor P01 frequently - since I have been wearing these regularly anything sub 40mm feels tiny - which includes my favourite of recent years - my BB58. Size aside I prefer it on the strap vs the bracelet Im not a fan of bracelets that have the protruding endling.

the dial on these are amazing! Photos don't do it justice, congrats on the purchase! Based on your photos, I would try wearing it slightly higher on your wrist so that it doesn't get in the way when you bend your hand backward.

Beautiful dial, always wanted to see this in person.

Whats too big? Who cares.
"Sorry sir you cannot enjoy these watches because you were born with a smaller wrist". Heck with that mentality. If you like it, own it, enjoy it and wear it! Its not like this came in two sizes and you can pick the better fitting one, this is the only speedmaster size option with 'aventurine'.
