Feedback on north Wales touring route?

Hi guys, I'm going to Wales for a week soon with my 120mm hardtail.

The goal is to join a friend close to Bangor at the end.

I drafted this route, leaving on a train from Liverpool then I'm gonna start by a day at one planet MTB then zig zag my way towards Machynlleth to ride up north mixing up the traws eryri/sarn Helen/Llwybr Ucheldir Eryri

Might also try to squeeze in a few bike parks (can't remember the names but not dyfi, too hard for me)

Trying to see a lot of nature, visit some trail centers.

Any feedback on my route from locals or ppl who traveled there ?

I have 7 days so about 50kms per day seems manageable.
