I like the idea especially the part that you put hearthstone into the animation. since they both are blizzard games i thought it was a great job.
the sound effects and music seemed allitle bit low on the beginning
the animation was kinda cute and nice for yor you being a begginer
flash for the gun shoot of the death blossom to bright
i know its your style but its kinda strange to see mercy headless whitout a neck and mc cree like rayman
buttt thats ok its good its ok good job
