Hi! In light of my recent update about changes, thought I should at least make some kind of bulletin of live examples of what I mean when the edits should closely resemble the design. 

Here I will designs I own/have owned as an example, along with explanations of the edits.
Please keep in mind some of these changes are for personal characters so I may have added traits that have restrictions. Be sure to check the info of the species in question before going ahead with edits!

__________________________

DESIGN ONE
-Base colors remain relatively the same with the removal of pink blush
-Gold has been tweaked to a slightly duller more sandy color
-Tail has been changed to solid dark blue to match the new dark blue & gold hair

DESIGN TWO
-The overall colors have been given a purple tint
-Dark neck marking was extended while additional lines were added to the white of the chest symbol
-Glove markings were shortened and a gradient from the hair color was added
-Color distribution on the fins remains the same with the exception of a white marking change on the tips
-The biggest change is on the legs where I have taken the glove markings and placed them there, as well as a marking resembling the chest area on the thighs

DESIGN THREE
-Base coat was given a slight red tint
-Are above eyes was darkened, gradient over nose given a hard edge instead
-Colors removed from ear tips, inner ears given a marking matching the chest mark instead
-Diamond placed on hips and chest marking

DESIGN FOUR
-Base coat was brightened and given a slight red tint
-Hair was changed to white, eyes were changed to green
-Accent changed from pink to red
-Flower and drop markings remain the same, but lace markings slightly tweaked + removed from inner ears
-Black distributed more throughout the body and tail, and rose motif carried down the tail
-Green marks removed from upper hip fins

DESIGN FIVE
-Base coat was darkened with a slightly brown tint
-Yellow accent tinted slightly more orange
-Most markings kept intact with finetuning on the symbols of the shoulders/chest area
-Black stripe markings consolidated on arms/legs
-Extra lines and dots borrowed from existing parts of the design were added to the sides, arms, and legs

DESIGN SIX
-Base coat & colors kept the same aside from extremely minor tweaks
-Gold trim, arm and leg markings removed
-Side markings changed from pinstripe to solid blocking
-*Note: A design with so much identity removed has a chance of not being approved, but because of the existing colors and unique aspects of the design left intact, something like this is fine.
