The central logo is taller than it is wide, making it difficult to use in horizontal elements. You could try this sort of layout:
Monster&Me
All on same line, roughly the same height. It would also help if there wasn’t such a large discrepancy in line-height between the “M” and the rest of the title text.
The small details (butterflies and faces) also won’t do well at small sizes. You could consider using them elsewhere in your branding? Like maybe give Discobot the name/avatar of the old dude (assuming he’s the “Gandalf” of the group…)
