Im using STM32F103 C8T6
I don't know much about the circuit, but I suspect if you hooked everything up correctly it will work. That being said, a few gut feelings on this:
1 - I wonder how having different trace widths will affect things, such as in and out of C8.
2 - I believe you're supposed to put the crystal as close as possible to the chip. You also may be able to find a physically smaller crystal if this matters to you.
3 - Maybe fill the top with a ground plane along with the bottom?
4 - If you do that, you could consider using vias to stitch both planes together in multiple points.
5 - Consider adding an onboard LED for easier troubleshooting etc.
6 - When you order, consider getting a stencil or even having the board house assemble it. Yet to get the board back, but just put in a PCBA order with JLCPCB and it was surprisingly economical, though I left the through-hole components off.
Again, those are my gut feelings on the board. Take them for what they are worth!
Interesting comment on video I put out a while ago about an arcade button MIDI controller: https://www.youtube.com/watch?v=WzuLe1t8wpw
Not sure how serious the person is, but was interested in actually buying it. As seen in the video, I put around a day of work into it, and there is maybe $75 in parts in the device. I basically said to make me an offer, but how would you handle this? Obviously I don't want to under-value myself, but I'd kind of like to make an upgraded version and it may just end up around my garage anyway.
Thoughts?

MIDI Arcade Button Controller Case [1-Day Build]
I made MIDI arcade button music controller out of a Pelican-style hard case in one day. Includes rechargeable USB battery and 8 note inputs plus power/auxiliary buttons.
ToC:
0:00 - Intro, finding components
0:54 - Build plan
1:22 - More finding
2:02 - Wiring start
2:42 - Cutting the Apache case
4:18 - Option and power buttons
4:56 - More wirin...
Hi,thanks for the insights
1. For the led,this is a great idea.
2.trace width difference, the set width can't connect to the chip direct due to chip pin clearances.I actually thought a out it but this is simple device and not a high frequency device,so I ignored that 😅
3. I will definitely add more vias and consider the ground plane on F.C.
4. For the crystal, I have 2,size feels okay though, but wanted to have the 32.768khz for accurate timing.
