I'm going to give some observations. Please don't think I'm being very critical of you because I think you are doing great work on this. I want you to succeed. We all understand basically how things work. If an image, sketch, or drawing shows something that doesn't work, it causes us tension. They have found this to be true with crows. Show them a sketch of a bird standing improperly on a branch that is not connected to a tree and they get really confused. I happen to know that also affects our parakeets but that is another story. So, it doesn't look quite right to you because there are some construction problems.
Think about how this is being built. For starters, the material would be on the outside of the poles. IF one actually wanted to put the material on the inside of the poles, the material would sag at the tie points. Especially on the lower half, there would be a significant gap between the material and the poles. Take a look at pics of Mongolian tents and teepees. Even better, go on youtube and watch a video on how to erect a teepee. Survival Lilly has one of her working herself silly with a friend trying to erect one of these things. If the material is tied from inside the poles, the holes where the ropes tie are stress points. In a short period of time it will rip. Also, it would be extremely hard to erect inside the poles. Much easier and more durable outside the holes.
Next up, the stick bindings. Good idea but something is not quite right. On a teepee, the bindings are at the top, but beneath them is a flap that also secures to the tent. Again, watch how one is erected and it will make sense why things are the way they are.
I would think a single piece of material with the skins sewed together would be appropriate. You want all your parts connected so you can erect this thing quickly in the field. Make sure everything is stitched except for the flap. Keep all your openings on the same side. The stick bindings and the flaps should all be in the same panel on the tent. That is where you know you will get leaks and you can deal with it by positioning or a separate piece to shield the holes from the weather.
There needs to be a support structure for those poles. There is no way they can be freestanding. You would need a hoop inside halfway up to keep the poles extended and not pulled down by the tent and a hoop at the top to keep the spread there. That is why the teepee only has a binding at the top, the poles are resting on each other. You start by binding three poles on the ground, erect those, then add more poles and bind again. Again, watch the videos erecting teepees. Maybe having those poles mesh together at the top and bound will fix it, but it would still need a hoop in the middle. You don't need to make the hoop, just show its impression on the fabric of the tent.
Of course, it's fantasyland and you can do whatever you want to see. Artistic license is used all the time. Look at Warhammer. There just ain't no way. But it looks cool. Artistic license is fine, but if something is too far off, it will nag at you that something is not right. Get the engineering right and the art will shine through. Get the engineering wrong and nobody sees the art. Just my opinion. I've been told I'm an over-analytical jerk anyways.
I've been sick for 2 1/2 weeks barely able to view posts then post this long thing. I think I need to lay down because I wore myself out.
I hope I have been helpful. This is looking good and I really want to see this succeed.
