Hey, really sorry for the delay. I've been distracted by spring break I had the past week, and currently, GDC. Here's what I've made (I had to remove the bushes because they were too difficult for me to figure out how to make :/ ) [link]
Anyways, hope you like it! I definitely learned a lot from making this, and I thank you so much for letting a beginner like me to have a chance to work off of your concept!
I seen what happens with house look very cool) I like it!
When i texture bush I usually take the sphere and just draw different spots that would be in general they were similar to the leaves. You can also attach a pair of plane with separate leaves as if sticking out of the sphere. And when you done it look like cartoon bush, like on concept art.
