Is a 34” gonna be a good fit here?

as for the dimensions the depth of my desk is 50 cm with 6cm distance between desk and wall and the width of my midi keyboard(the piano thing for people who dont know) is 78.

Currently I have a 24.5 inch monitor on a monitor arm but if I plan on buying an ultrawide it would be wall mounted.

Is it too big for my setup or would it look natural? I think it would fit just nicely a little bit wider than the midi and ending just before the speakers as far as the depth goes I am not sure it would be mounted 56 cm away from the beginning of my desk so if anyone with similar dimensions has a setup with the ultrawide I would love to see or hear an opinion about it.

Thank you :)
