Downpipes does this look right?

Storm water pipes were installed before guttering etc. Location of the downpipe didnt line up so they came back to "fix" it. This doesnt look right to me but i don't know if its not to code. In SA. These are on the boundary of the garage and the pipe runs underneath the slab. I would assume you want as few bends as possible as otherwise you can get back pressure in a heavy downpour. Any help please. Want to fix before paths and driveway get concreted over

Pipe goes through the slab to the left of this photo and the right comes towards the bottom to pick up drains
