All your new stuff seems really similar.
Christmas one the effects dont look that great. Also the colour isnt appealing.
Also keep it a coloured one. V2 and 3 doesnt work well.
Blue girl sig is nice, but i suggest adding a small amount of efx to its. possibly bubbles that match the colour scheme?
I think the color Christmas is good, maybe just tone down the color a little and get some of the other colors to POP with some gradient maps, like a black/white gradient map or desaturate to tone down and a black orange and a few others to make some colors POP!!!! of course you would have to mess around with opacities and layer settings.
