The only yoyo that I can even associate being similar to yours is YoTricks x Sengoku Forge 1st proto (bowl cup, profile is literally a YYF AlDream).
And even your design is already different due to the rim shape and response area step. I think you’re safe from anyone calling it similar to another yoyo.
Take a look at the Yoyo CAD & Prototyping Adventures thread. It is a gold mine of information for anyone interested in yoyo design.
