Sneak Peak at my First Rendered Still!

I've rendered out and composited together all the render layers for my first still. I spent a fair amount of time on it to get it right and give me an idea of how to go about the others. Placement of the camera took the longest as after deciding I wanted a still of the steam train going past the tea house switchback railway tower I then had to get it to fit with some nice mix of foreground, mid-ground and background elements. This would help add depth and when I pan in/out in after effects will really help add interest. It was also something I remembered was key from the interim crit.
Depth of field then popped my train into focus like I wanted and then some particle steam which I ended up doubling up on layers for when compositing because it wasn't popping out like the train.

 

Let me know what you all think!
