it looks a little dated (stock template? rushed job?) and if you're trying to woo potential clients you should take the same care in the design of your site as you would for the services you provide. Right now it's not sending the message that I'm thinking you want your (potential) clients to get or that your slideshow seems to imply (abstract concept to polished rendering/design)…
--get rid of the frames/tables; use CSS and layers
--simple is usually better; let your work stand out and not be overshadowed by the poor/distracting site design
*edit: your work deserves a better site
