Feedback for my first variable typeface

Hello everyone, this is my first post and also my first variable typeface project. 

The design was born from a client's branding project that I later developed into a custom typeface.

The client is a well-established running brand and retailer in Rome, Italy, and the identity/typeface suggests the intersection of individual paths, hence the "softness" of the curves.

The family is designed to cover multiple weights, from ExtraLight to Black.

I'd love to hear your technical feedback, as I'm self-taught in the world of variable typeface design and this is my first real approach to type design.

Any thoughts are welcome, thank you!
