What do you think about a ramp that goes from 4 wide at the base to 6 wide at the door for the shed?

I’m working on putting together a concrete ramp for our shed, mainly for my riding mower to use. The door is 6′ wide, but I only really need a 4′ wide path for the mower. Originally, I was thinking of going with a 6′ wide and 6′ long ramp, but that would require more materials.

I’m also considering a 4′ wide by 6′ long ramp, but I’m worried it might not look great. What do you think about a ramp that starts at 4′ wide and widens out to 6′ at the door? Would that look okay or just weird?

I’ve attached some photos for reference. Thanks for any input!
