There are a number of problems with it.
You can't read the text without enlarging the comic.
It takes more than 2 seconds to read...you probably aren't going to get that much investment from anybody unless they already know what this is, and care (they likely have an active desire NOT to see this).
It is CONFUSING...I get that this has something to do with running SQL queries from within excel, but I have no idea what is going on in the comic. Is this the guys boss? Is this some vendor? Who is this person and why does he look so radically different than the guy behind the laptop?
I'm still not even entirely sure what your product does...doesn't excel have the capability of doing this natively?
I think if you wanted to do an ad...big bold letters that say "RUN SQL FROM WITHIN EXCEL" would be MUCH more effective than this...
