Need help finishing sleeve

So, I’m looking for input plus helping design/putting together. I’m far from artistically inclined and not the best at explaining myself, but hopefully pictures will help. I currently have the front portion of my arm done, picture included(clouds,mountains,river and boat). And I’m wanting to finish off the sleeve by getting the back done. I’m wanting to do a compass at the bottom of my arm near the wrist, then above do like a wooded area with two paths splitting different ways with like light coming off a crescent moon at the top shining through the forest. I’m not really sure if this will really flow well into a “sleeve” or will look right with what I already have, but I’m hoping someone can either help me out to make it flow together and look good or I’m just open to ideas in general of something that would flow well with what I have! Pictures included of my current, and sorta the idea I’m going for!
