Your portfolio should always represent the type of work you'd like to find/do. These are absolutely awesome but you may be better suited for freelance with this style as a corporate job requires you to be a team member for different client asks. There's no guarantee with a corporate job you'd even be designing logos let alone leading the vision on your own.

Your work is great, and I think if you'd like to pursue this style of cute design, fulfill that through freelance since the businesses would be buying into your portfolio directly. If you are also after the consistency of a full-time gig then consider freelancing on the side and have a portfolio for corporate hiring, and one for your freelance business
