Ughh, Recolours ¬¬
As Ray pointed out, you forgot to recolour some of the outline parts.
I like the colour scheme you picked for Magmortor, I feel the pink and light blue compliment each other nicely.
Remember my friend, recolours are all good and fine for a starting point, but they're not all that difficult or amazing, after you feel comfortable that you've got recolouring down I suggest you move onto edits.
