Bloodborne - a (bloody) love

Once more again , i did a fan art of Bloodborne , pretty simple nothing special .
A friend of mine said once , why don't you just make some picture of girls making cute stuff like the heart with the hands? that's easy and cheesy!  
and i thought : well maybe in my way .
Being an Hunter is quite fun except that you have to swim in rivers of blood and kill monsters with bare hands , pretty dirty stuff . This is why she seems pretty annoyed , blood ain't easy to wash away .
well it's pretty obvious that i like bloodborne and i could die waiting to play it .
the biggest issue of this draw were the color , i don't have many different pencils so i can't make many shades of grey.....(not 50...) .
The one in the right is the plain doll and the guys on the left are the ....tiny (adorable) messengers. 
I didn't want to make anything flashy in the background but 

Any  advice , tips , suggestion , criticism by anyone is welcome  .
you can help me to improve  .

feel free to comment and fav 

p.s. yes , i really have to buy new pencils
