For the palm tree I wanted to really ensure that the asset looked natural as well as having the same style as the rest of our game so I took quite a long time editing this from multiple angles to try and ensure that no matter what angle you view the tree from it doesn’t just go straight up.
For the general Modelling technique I started with a simple cylinder and then scaled the top of it to give it a more natural feel for a chunk of a palm tree. I then extruded out from that and scaled it again, rinse and repeat, until I had the general size I wanted for the tree and then I went around the asset pulling the smaller chunks out to try and give the main angles of the model a unique S curve to them. For the leaves it was just planes I had edited and curved which I then copied, pasted and scaled to different sizes to make sure it didn't look to uniform.
