LZ Logo

Working through the process of coming up with a personal logo. My initials as of mid-May will be "LZ", so I am working with those letters. Came across an interesting concept after drawing these letters together of it looking somewhat like a lightbulb. This then sparked the idea of an "idea lightbulb" and incorporating that into my style of graphic design/logo design (symbol marks).

Thoughts? Readability? Your comments are appreciated :)
