Fun. Can't usually roast or provide honest feedback because feelings about customs.
I'm not a design guy so unfortunately sometimes I can't ascertain what would work, but simply point out what's broken - sorry. But on that note - the font, nope. It's something I would use on a report in 4th grade using word art in Microsoft Draw. I think the overall style of it can work for sure, the strokes of the R remind of me resort world R. I believe it's the thickness of the lettering and the black shadowing that feel a little dated/cheap to me. But I def think it can be worked with and some small changes to make it feel modern and clean while keeping the hand written cursive feel, similar to a RW design.
Regarding the fireworks themselves, not horrendous. They are rainbow, which would be very difficult to make feel clean, mature, sharp, focused, and somehow also difficult to make vibrant. They also look like palm trees. If palm trees is intentional, fantastic, but then you're taking from Palms and it's going to be near impossible to mix that with colors, with the fireworks, and with the working title. I'd remove the tails from looking like palm trees.
I'd start by trying 20 different iterations of fireworks to see what works and what doesn't.
Below we have customs with fireworks that look like they wrote in to chat gpt with the prompt: "Please make very expensive
CPC chips that look like the American flag got a horrible stomach bug and threw up on my poker table".
It's super rough, but that's what customs are - something that the creator finds beautiful. I think the only thing these chips do well from an objective aesthetic standpoint is the fireworks (I have no clue what the red thing is on the other side) on the one side fill the inlay well. If you're going for clean and empty outside of the fireworks and name, perhaps toy with the idea of being an overhead view of the explosion or an in every direction explosion with the mid point being closer to the center of the chip.
I don't know of other fireworks chips, but the Celebration's come to mind. I love these and would absolutely love a cash set of them. Below is a horrible photo.
I like them because of the contrast. What a serious looking chip - that is a means business no frills chip and and no frills edge spots and no frills colors - that's a pretty plain, easy to read, bolded font with a no frills denomination. All to then be filled in with the frilliest of designs, just random confetti and strings haphazardly placed of every color.
To me, the juxtaposition is banging.
YMMV, everyone has an opinion and they're all different.
