No not really, I am not an artist so I have a hard time imagining it. I can adjust my game to whatever creative vison you decide to go with if you decide to make it but let me tell you what details I did have in mind.
I imagined the trees in my game more like outside tree houses hanging from a big tree like some sort of fairy type thing so all natural looking wood and stuff, definately lots of leaves and stuff hiding it from veiw from the ground, maybe go inside the trunk of the tree every once in a while.
Again if you decide to follow up on my request thank you so much! Go with whatever vision you can picture that you think would sell well for others as well I don't want to waste your time with something just for me as I can't really afford to pay an arm and a leg here so I'd hate to waste your time with something nobody else will want :)
