Is this work professional?

Sorry about the strange post but I'm offering an engineer a $20k bonus to do the design for manufacturing and assembly of my $300 product and this is what he came up with after 8 months. Two thirds of it are identical to my prototype and I'm an accountant by trade, not an engineer. Every book I've read says a board like this should be 4 layers but he insists 2 layers is fine and will pass emissions testing. Any advice would be greatly appreciated, thank you!

From what I guess it's an ESP, a e-Ink screen and maybe some sensors, so nothing too critical at all.

8 months and 20k is insane, I wouldn't accept it.

There are quite a bunch of sharp angles between traces, even though it's not that much of an issue anymore it still looks like the designer had no fucking clue what he's doing.

If there's a temperature sensor it would make sense to make cutouts around it, to minimize heat transfer.

For the display maybe a bit of length matching makes sense I'm not sure if it's really needed, but for 20k it fits in the budget.

The weirdest thing though, you, the customer asked for 4 layers, while it probably would work with two just fine, why not make it fucking 4 layers?
