I thought that we could further expand the guild halls making them have a area in front of the building. This area would be able to have monuments, statues, furniture, plants, ponds, streams and such

The more expansions the GH has the bigger and prettier the outside of the building is.
A guild name at the entrance would make anyone feel good about walking into the building.
More room inside could also add more room outside or they could be bought separately.
A massive new furniture update could follow this, different style plants ( flowers, trees, wall climbers ), swings, wicker furniture, paintings, rocking chairs, ponds of different sizes and shapes, fountains, mannequins wearing our old gear scattered around the courtyard&GH, guardians with spears at the entrance that cross their spears when someone is not allowed to join or even ask for a password and monuments of the great old kingdom of Almire.
Guild hall expansions could feature rewards such as bigger and bigger flags hanging from the guild halls walls which gain room for decoration with upgrades ( upgrades such as, lights turned towards the walls, flags of different sizes and designs, statues and ofcouse a guild name at the entrance ) and maybe a massive balcony behind the 5th floor rooms overlooking the clockworks. Balcony and other rewards for a fully expanded guild hall would make this much more appealing. Personally i find fully expanded guild halls way too expensive and ugly, a big number of rooms inside, they are bound to repeat themselves to be furnished and end up being boring, having a balcony and a courtyard would give it the variety it needs.

I open this suggestion for tweaks and further suggestions of the community and hoping it gets noticed by the OOO's designers.
