A crystal/ice consepart test seeing how color ice would look by using different textures and rendering for crystals and ice so they'll be different from one another. IDK. What do you think? Color ice magic references is difficult to find and what I can find is a light purple for references.

From an 'not even amateur''s point of view they all look pretty. :)
To say anything more about it I would have to see the crystals/ice in the context they are going to be used.
Your peers in the Art forum would probably have better feedback:

In honesty I kinda forgot about the art forum at the time of posting this but for use mainly backgrounds and attack animations?
