Some people may didn't notice but Faven changed the default colour set up from pretty much all yellow to what it currently looks like (you can still see the original look in the 3D preview screen) and I think it was a good decision because

a) the colours just looks way better in general
b) yellow is a difficult colour to work with, especially in Warframe and
c) the original one didn't look as versatile customizable (unlike this one) since the colours were pretty much the same.

At first when there still was the yellow set up I wasn't as convinced as I am now (the colouring example pictures didn't really help either). The new scheme turnes the skin into something that actually resembles a respectable fighter instead of a slim Garfield on a battlefield. Originally I didn't even like the LImbo Graxx skin when it still wasn't out but now it's one of my favorite TennoGen skins because of it's uniqueness while still fitting the Grineer style. The same goes for this one except Faven didn't have to change anything on Limbo Graxx in order to make it look good. This one just had a disadvantageous colour scheme...
