not bad
but I would take a strong look at making the logo more professional...
Consider utilizing the themes default slider. You may also want to turn off the click-able large image on the main page as there is not a call to action there..
Make the footer blue or grey to contrast if from the other pages.
lastly, since you barely modified the original theme I would consider switching "designed by" to "Premium wordpress theme integrated by" or leaving it out (IMO).
