Agency logo

looks good but the main text is not aligned with the subtext (or is just my perception). Remove TM if is not yet a TM

Why is the A highlighted?

The first impression is good but when you look closely you can see the little imperfections like, the subtext should be smaller, the width of the M is smaller than the D and A, This is not a bad logo it just needs some little work.

My thoughts on just the design: I like the way the A overlaps the D but by doing this you are condensing these 2 characters and then the MM is extremely wide so the balance is way off. Perhaps you could overlap the MM in some fashion similar to the DA. The curve on the ascender of the D is a nice idea but it needs to be either carried through the rest of the design or dropped, it looks like an afterthought as is. The colors are nice. I think the subtext is a little large and the alignment on the left seems like it is sticking out a bit too far. Your ™ should match the font in the subtext.

My thoughts on the branding: To be honest, Design and Media Marketing seems like a tagline rather than an actual company name. It's very generic, kind of like naming a restaurant HAFF, Hamburgers and French Fries. It's strange that the character that is highlighted the most in the logo is the A which represents the least important word in the name. The subtext looks like it is begging for an ampersand but of course that wouldn't make sense with the acronym. I'm guessing this is for yourself as a freelancer? If that is the case I would reconsider the name.
