Yes, I have to say that the unprofessional vibe given off feels absolutely horrible to me. I'm surprised that the designers of the site appear to be the same as previously, since the previous style and vibe felt very good to me, and this feels so much like the opposite.

The current crop of clip-art would really need to go, I'd say. Nothing looks as hasty and unprofessional as stereotypical clip-art. You especially shouldn't with your clip-art choices communicate that you're a very formal, ordinary and uncreative men-in-suits organisation, since you're really not (and if you were, who would think you competent or even sincere in undertaking such an unusual mission? Stereotypical and ordinary men-in-suits are the antithesis of creativity, exceptionality and thinking-something-that-isn't-a-politically-correct-cliche).

The current site design could perhaps be made to rock if all the clip-art was changed out to a new theme that was creative and original (and you) and wouldn't really look like clip-art. Some associated changes to color scheme and fonts might be required, but perhaps not a complete redesign.
