Here's some critique for you,
I love the colors used, although the colors on the paw (the blue, red and yellow) seem out of place on this design, not really matching up. I would suggest using the purple that was used for the nose to also be used for the paw pad and tongue as well. Or even use the pale red on the entry's back for the mouth. Those colors do fit for the mist rings, just not on the body design unless otherwise shown than just the paw pads.
The design looks great so far and I love the mist rings!
I don't believe coloring the shadows is allowed yet or it would at least count as legendary. The only shadows that can currently be colored are the eyes.
A suggestion for future entries is to list the rarities of the edits, it helps clear confusion especially when the flitz is being bred(for real adopts).
An example for this flitz (with a bit of extra coding)
