This lovely piece was done by Mallaury:

"So HI I'm Mallaury knows as Maltes Mc Gee on internet (I  mean if we can tell "knows"), I'm in my fourth year in a 3D animation  school in Paris, I love drawing and modeling characters, the goth  fashion of the 80's and nose (yeah weird right, I don't understand it  either) also I have a little (huge) obsession with everything vampire,  serial killer and gore related, which leads me to what make me discover  Transfusions! (a funny story if you tell me)

So I  think I first heard about Transfusion back in 2014, I was still in  high-school and was too confused to search for non French comic so not a  good start. BUT that was without a small coincidence that happened, one  of the webcomic artist I was reading received a message from a fan  saying that her characters were strangely looking like some from another  webcomic (red hair vampire, shy dark-haired character being attacked)  she immediately freaked out because she never had heard of it and didn't  want anybody to think that she copy the characters (BTW except their  hair are not that similar) , so she share the link of the web comic and  OH Boi how glad I am she did! I literally read the whole thing until  morning and read it over and over waiting for the next update. Basically  I discover Transfusions because of a weird coincidence and really enjoy  it right away.

For the guest art part, I guess first it was the  design of Mark and Jess, I don't know they just seems so nice to me and  then I discover their relationship with Joa and felt super sad for him  (the whole moment when he cried blood remembering about his past, demn i  never cried so much) and I don't know I just want to draw that part of  his life that make me react so much.

Omg I feel  like this is getting so long and it's so late by the time I write that  but yeah just to say that Transfusions really marked me and in a way  that I couldn't explain help me choose to work in a art field when I  didn't know what to do with myself ^^'

Hope y' all are having a wonderful day!
Btw my social media are all maltes_mc_gee (so on Instagram and Twitter basically)"

Thank you very much, Mallaury!
