hey everyone ♥ I plan on painting a picture with acrylic paints soon & it's honestly going to be my first painting i've ever done so I want some advice on how to make it the best I can make it. And I was just posting this if anyone here can give me some tips

or link me to some tutorials that you think i should follow for it

This is the picture I wanted to paint (it was a picture I made with the sims 2):
https://i.imgur.com/mM95HI3.png (<that's me/Joe & Freddy Krueger) I plan on painting it on a black canvass so i dont have to paint the whole canvas black, and i was also going to draw the shape of everything on the canvass with a white pencil first, then paint over it with acrylics.
I was also planning on using a hair dryer to make the paint dry faster (anything i should know before doing that?...)
This may seem far-fetched, but I honestly want the painting to turn out to have the same quality as this picture, which is what it's kinda bassed off of:
https://i.imgur.com/RLFNbaN.jpg (or at least close to it as possible)
I'm pretty good at drawing, but it's the mainly the shadding that I might have trouble with. Also, I want there to be some differences between the hand painted picture... The picture is still supposed to be dark and creepy looking
BUT I want the eyes on both Joe & Freddy to be larger & appear to be buldging out of their heads, kinda like this picture here:
https://i.imgur.com/FBCH8W2.jpgI want Joe's eyes to show fear/terror & Freddy's eyes to show evilness/anger. Also the shadding on the eyes is one thing i need to look into because i don't just want them to be white and red circles.
Specificly, I want Joe's eyes to be open wider and to look TERFFIFIED like the girl/Nancy's eyes in the other poster. I remember I showed the sims 2 picture to my adoptive Dad & he told me that Joe's eyes in that picture look more like he's in pain than he's afraid, but I want him to look afraid.
Does anyone know of any tutorials i could follow to paint eyes properly?
and to get the shadding/shadows right in painting with acrylics?
I will be painting this in a couple days as soon as my paint-retarder comes in the mail (i've seen tutorials on how to use that also, but if you guys know of any more i can watch when it comes to painting stuff like this, feel free to link them or share your tips on that.)
ALSO any other tips would be greatly appreciated too 
Please help

Welcome to you.
Have you had a look here https://www.deviantart.com/

For a first painting that's a pretty scary subject. I'd try something simpler first.
@dencal recommended deviant art. I've never been there but, from its name, and from the image you linked to, I think you might be more at home there.
If you want to paint realism al la DMP then I recommend you start simple. Paint an pear or a mug like in in Mark's free videos for beginners. Once you master that you could then run amok with the scary, deviant stuff with greater confidence.
