What TIG says is ver important. Always model to real scale and separate your geometry by grouping parts together (or - when there are more instances of the same object, use components).
Texturing should not be an issue. The part over the entrance can easily be textured with a projected photo of the thatch material and also the conical end is not that hard. We can get back to it when you finished those two parts and already have some good thatch material.
