Thanks pyxelbit,
I will be sure to add a uniform light source. The orbs are supposed to be 9 realms / worlds that Yggdrasil connects.
Here is where I got the idea for that. Found it on google images while I was looking for references.
The thing I am concerned the most with is what to do for the top of the tree, which style of leaves to go for, will have to experiment with different styles and see what I think will fit the most. Although there is a lot more to do before it's time to do the leaves so I have time to think about it. If anyone has suggestions for that feel free to link some references, so far haven't any that I like.
P.S. After I previewed the post I noticed that someone edited Pokemon on the picture
Edit:
- Thinking about making all 9 orbs a unique light source or at least the main orb ( the one in center of the tree ). Still deciding wether to go with that or another totally different option.
