Team 'Bloody Love Punch'

Meet the crazy team of characters I designed for Endling's Hollow project. It is a future MMORPG game that's based around the classic halloween monsters. Now, I never played an MMORPG before but I have played a number of RPGs and MOBA's so I think my ideas can be applied to the game.
Character infos:
The Vampire is a fierce, lone wolf type ranged character. She's a renowned beast hunter and she studies the anatomies of beasts to kill them in the fastest and bloodiest ways. She aims for the most vital arteries of her enemies and rips them open with her special bullets that break up into pieces when it hits a target. In the game she would have an ultimate ability called "bloodshot" which is a low chance but very high damage crit. 
The Mad scientist girl is a crazed summoner/support type character. She is all about love! Her skull-droids "kray-Z" and "luv" have the abilty to gain control over neutral mobs using the power of love. Her electric dino robot(that doesn't have a name sry) would either have the abilty to slow down or stun enemies with electricity. The Mad herself uses a wrench that heals a single ally in a short amount of time but in order to do that she has to start whacking you with it, so fucking deal with it.(All credits to MagpieFreak. She came up with it.xD) The abilty in the game would quite obviously be called "Tough love".
The Zombie is a mobile and energetic melee character. He's fast, he has the abilty to dodge enemy hits and deals massive amount of physical damage. Simple and strong.

That's about it. This was supposed to be an entry for a contest but I didn't make cuz I was very short on time. But if I had more time I think I would've developed the vampire and the zombie more and actually tell a story with them. Also the crazy girl's wrench would be way bigger and fancier. Though still I'm pretty happy with how this came out. I had no reason to rush since I was already late so I decided to go ham with the colors and experiment a little bit. It did work out quite well but the background was a complete pain in the ass. I literally spent a whole week trying to make a decent looking background but failed. And I ended up with a simple vector type background which looks ok but it could've been something way better.  
Anyways, I hope you check out The Hollow Project and maybe contribute to it. And I hope you like this piece.
Thanks to MagpieFreak for the help. She helped me a lot on the background and on a bunch of other stuff too.
Characters belong to me.
