The actual site design is great. It was one illustration.

Why exactly should a single image on the front site make or break your technical case? Have you considered that this might be an indication that your technical case was extremely weak? Or maybe that you're being hard on anyone who exhibits even an inkling of whimsy on their project?

I agree with you, of course, but I think you're underestimating how important appearances are to these middle-management types. Especially the ones at service-based companies. They will visit the website to research a tool that I want to use, and if it doesn't look professional, it will get rejected regardless of any technical argument I make. This is true for everyone, not just me.
