Okay - bottle of liquid mask arrived today from eBay

.
Now - probably the hardest decision - what to spray?
Where do you guys get your ideas from? Are there sites dedicated to r/c shell spraying that I can look to for inspiration and tutorials? Got to try and get my shell and wing done before Wednesday. Nothing too fancy - just a little bit individual and more advanced than a 3 colour rattle can "colour merge" job.
Any help is much appreciated!
PS - Yes - I do have an airbrush and I'm not afraid to use it!
