Fire and Ice. I like how they are together but still seperate pieces. They always work best as characters when you are contrasting them.
You did that with their facial expressions as well. Normally I like Ice to be the one smiling, but given the "ying yang" theme you are doing here it makes sense as well to have their facial expressions contrast as well.
I would have liked to have seen more of Fire, not just her upper torso and head in green flames. I like what you did, but I also like to see the character. I do like the half-hidden arm in Fire's fire.
Though back on facial expressions for a bit you really did capture what I feel are their personalities.
I love the vague anime style to this. They are two characters that really could benefit from an anime/magna style presentation.
All in all I really like it. It is cute and fun just like how I like Fire and Ice.
Thank you so much for the critique! You raised some points that I didn't even realize about the cards (eg the yin yang aspects)! I agree, Ice is the one who usually should be smiling but I was thinking of how serious she always gets when fighting, so that's what I showed here. As for Fire, I imagined her sometimes just gleefully indulging in her powers; hence why half of her is engulfed in flames ^^
Again, really good eye! And thanks for the compliments as well. <3
