Trying to find a design that suits me, and looks professional. What do you think?

I'm going to be using this as my logo! Err, like a kind of logo. More like an image I can post places to try and gain attention to my Web dev work stuff and gain more clients.

I'm kind of scared it feels too 'artificial / agency' like instead of personal like I try to sell myself like. What do you guys think? Any suggestions / ideas or critiques? Thanks!
