"Tree of Life"

In my quest for creating myself through my art, I have decided to try nature (not really the first time I thought of that!)  instead of people.  This is what I came up with in this format.  I like the simplicity of it and yet I wonder is it too simple?  Everything I have done in the past has been so complicated and so it's almost difficult for me to be more simplistic.  That's not to say that I did not put a great deal of effort into it just an observation really of how I work.

So, what do you think?  Was I successful in my quest?
Does anyone else struggle with this issue?
How do you handle it?

Thanks to everyone who reads and comments!  It means a great deal to me!
