I'll go another step on the logo and say - change it. It looks cheap. The site looks OK but nothing special BUT the slide show is effective, perhaps START the slideshow with one of the other slides as slide 1 is uninviting. Good luck
Overall the site looks very professional. Its great design. It runs very smooth also. The logo could be a slight bit bigger. But thats all.
your website looks stunning, very proffesional design and the contents are nicely done.... overall perfect keep up the good work
