I tried different shield types in A1, A2, A3 and some variations in proportions. Since in the first three the head was quite big it looked a bit cartoonish, so I tried making it smaller in the next three variations
In A5 I tried something interesting as in using that back-element thing from Gatotkaca as some kind of container for the baby orangutans. Tho problem with this approach is that there will be much detail behind the back of the champion so that giving the champion many head acessories would be a waste.
In A4 I gave the champion some Gatotkaca inspired head accessories and placed the baby orangutans on the shoulders.
Overall I like the shield from A1 the best (it looks the closest to how the Nias tribe are using it) and I like the concept from A5 where the baby orangutans are in that back-thingy. I am a bit conflicted since I also like the head sillhouette of A4 so I will be doing more exploration on this.
