Well I always think that it isn't to hard to work something out, it's hard to come up with a idea to work out. The design is simple and it fits perfectly. If you add all kind of effects and filters the logo would only get messy and probably unreadable.This design suits best for your current site I think. Though i,m not sure if it fits with your current colours, but your already working on a new version right?If you need some help with the site just PM me.
