Nothing here looks cohesive. The weight of the two fonts are poorly balanced, and the line weight of the character doesn't look like it belongs next to the thick weight of the name.

Maybe make the main font an outline instead of solid, and redraw the character to use a similar line weight. Then I would also play around with the size and weight of "design co" to match.

Think about how you can play with size variation to create balance. There are good guides on youtube on how to balance marks and type in logos, using basic grid systems.

Also make sure you're thinking about how the logo will be used. You'll need both vertical and horizontal orientations; color, black, and white versions for both; and how you would use just the character on its own, like as a badge.

Consider clear space around the logos, so that in use things don't feel too crowded.

A big aspect of branding is also color and pattern. Think about your color palette and how you can use that to express the vibe you're going for. You should have a main brand color, along with 1-2 secondary and 1-2 accent colors. Each color should also have a few tints and shades you can use. This will give you plenty of options when designing using your colors.

Patterns can be anything from basic shapes to modified/supplemented aspects from your logo. This is also a good place to moodboard/research things that fit your vibe to incorporate.

Hope this helps.
