Have to agree with the others the site as it is is much more appealing, its bright and clean, where as the new ones nice as they are just look a bit to green. I like the image on your present site as well, it breaks up the text.
Yes sorry, first thing I saw was too much green - and makes the current site look more appealing but I can understand you wanting an overhaul, we all want a refresh of our sites after a year or two of seeing the same site like the 4 walks at home!
But I think sticking with the clean white backround and reinventing a new design of what you have would be best.
I actually prefer the original as well. Not saying there is anything wrong with the new design but as mentioned the green needs to be toned down a little and the primary offers made more eye catching.....
Good design though and I must remember to speak to Khalid for some design work doing
