the wings and converter of the alchemist overlap in a very bad way.. Looks pretty lazy. You should make costume+weapon pairs that will not look like two pieces haphazardly merged together. A one winged costume could solve it and would go well with the theme of searching for your second half.
The mage staff isn't even heart shaped
The daggers of shadow look suspiciously similar to decayra weapon skin.
Hunter is ok. Guard got another top costume.
