The revised route looks a lot better, Ton.
I still advise you to place the start and end points on roads though, and maybe a few metres in the direction you're intending to set off / arrive from, just to guaranteee you pass through them. Especially the start one.
On the improvements front, they're good suggestions, but here's one for you in the meantime (because they'll not happen fast, if ever):
- Get a stylus. Something like a basic Wacom one is cheap, pleasant to use, and it's a pen as a bonus:

Then you can see what you're doing under the stylus tip!
