Mangai Wall Attack [Brickonicle Concept]

This is one of many model I built as a set concept for the Brickonicle (Bionicle G3) Project, which was started by the TTV Channel.
As always, I added masks on the minifigures to show how they would look with these pieces. This time I also drew a background image for the set, please tell me if you like it and if I should do this more often.
This new Set has 929 pieces (including the 5 masks)

The new set contains the Mangaian wall, which is made of two segments, an Ice-Burnak with a sledge, a Ballista, that can be stored in the Wall, as well as the Minifigures: Tahu, Kopaka, two mangaian guards and tow ihuhan warriors.

The Mangian Wall:
The Mangaian Wall is made of two segmants, that can be taken appart to create two small walls. Combined they form one long wall. For the style and arcitecture, I tried to stick as close as possible to the style of my Mangai Defense Tower. You will later see why.
The two wall-segments can also be combined to form a thicker wall, that is not open on the back. The entire Wall can be opened or taken apart on different sides.
The first wall segment has a roof, two gates that can be opened and a Zamor launcher inside of it. The interior is decorated with light stones and some spears.
The second wall-segment is decorated with some red banners and contains a tresure chest, as well as the Ballista. It is decorated with spears, swords an some torches.

The Ice-Burnak with Sledge:
Because Rahi are greate and I wanted to do a bit of conflict in the box, I added a Rahi for the Ihuans. It’s design is inspired by the G1 Iche-Burnak.
With this Rahi I really tried to make it look very bio-mechanical, because I think the classic Bionicle aesthetics of bio-mechanical beings in the nature is a great style that G1 had, which I think sould be contained.
The sledge is monstly made outof a hero-factory armor-piece.It has a fiering crossbow, a classig MNOG-style red flag and the Ko-Metru Disk as a decoration. The Burnak is a bit of a spin on the G1-Burnak design.

The Minifigures:
I included Tahu and Kopaka, because some people pointed out, that it would make a set more desirable, to have multiple Toa, because they are the main charakters. The Mangai Guards follow the same design-concept as all my matorans. I tried to make them look a bit battle damaged and used colers like black and grey, so Tahu would stand out in an army of Mangaian Guards. For the design of the Ihuan Warriors, I added some cloth to their design, because I imagine they come from a very cold region.

Connection with Mangai Defende Tower:
The Mangai Wall can of cause be connected to the Mangai Defense Tower. It can be attached to form multiple different Fortress like structures.
