This is the official group of the Devs for now. The Silverate Devs can freely discuss about everything about the game as well as can submit their ideas, concepts, models and so on.
The gate has a gate tower on each side and two taller guard towers (posibly with balista emplacements) that are connected to the walls with bridges. Right and of the gate there is a knight carved into the wall (same on the other side), but I didn't put much work in him since I don't know how will Silverate knights look yet.
Also the guard tower's top is the same as the gate tower's, but I didn't do it since it takes 1-2 hours.

Also the towers are angeled at the bottom similar to the walls of Krak De Chevliers.
