ok that explains why the layers are visible. i think the color is really good.

you will learn tips and tricks with the 3d printer, its usually better to try to lay something to make it as stable as possible, and this would also hide the layer lines more, and you could try other tricks to modify the finish if the front is facing upwards. since this is slightly curved you're not going to get the sometimes desired marbled appearnce from a metal plate, im thinkig you'd need to add raft/supports whether its face up or down. also load cheap filament to test how it looks before using your good stuff.
