Very pretty! I really like the topography.

CC3 is a bit of a curate's egg: the best CC3 maps I've seen don't actually look like they've been created in CC3 or at least keep you guessing. The problem with symbol driven software (for me) is that it's very difficult to personalise your own style with them although with CC3 I have seen it done with terrific results - but I think it's more difficult with CC3 than say, a raster or vector paint program where you are forced to personalise from the get go (unless you're following a tutorial - but even then it's so easy to just experiment and find something new). Of course if you're not after creating anything that's particularly original and just want to put a map together quickly that looks pretty good, then CC3 is hard to beat.

I do like what you have done with your map though, it has a self containment to it and it looks like a fair bit of thought has gone into the placement of the symbols.
