Out of my comfort zone - need suggestions [edit]

I want to participate in this contest:

  CLOSED! Contest: Out of Your Comfort ZoneCLOSED!
The contest is now officially closed to new entries, and the judging has began. 
Stay tuned to find out what comes next!
Out of Your Comfort Zone
If you've been wondering why there's not going to be any new monthly challenges for the next two months, it's because we've been cooking up something big and new for you - a full-blown, dazzling and challenging contest with awesome prizes! 
The theme is: Out of Your Comfort Zone!
Have you been stuck within the same, comfortable borders lately? Feeling uninspired, lacking in creativity, or maybe you have simply been thinking about trying something new and fresh, making a change in the style you usually use while working on your art, trying out a new and excitingly unknown subject? 
Are all your works with models? Maybe it's time to try composing a landscape? If you've only done equine photomanips before, maybe you'd like to try a human model,

Basicly I need to do a photo manipulation that is new to me, something I have not done before.
So a mermaid or naga isn't allowed for me.

Does anybody has a suggestion on what to do?


[EDIT]
Here is my first attempt

What did I need to change/add?

Reasoning for this choice so far:
- I allways have a model -> no model
- usually I have a fantasy theme -> technologie
- little to no aktion in my works -> dynamic and action

next to consider:
- [I allways do] ->  [opposit of that]

I also could use a good title/name for this. I'm not nativ english and can't find a good word play.
So I'm out of ideas for this picture, without further suggestions this will be my entry to the contest.

If I win some deviantART points they will be invested in purchasing stock for more mermaids.
