That looks spooky! Happy Halloween!
Oooo Spooky! Happy Halloween! 
Looks a little too dark, I suggest brightening up the photo and making the colors more vibrant. It’ll make the sunset background, and the flaming pumpkin stand out more.
The vignette looks too dark too, but I assume when you up the vibrancy it’ll look less dark - if that makes sense.
Add more brightness for the lighting and add more effects
I think the pumpkin should be a little brighter and for it to reflect off your avatar a bit more, overall great though.
Looks a bit too dark, Maybe brighten up the image?
The pumpkin is also not bright enough. I suggest making that brighter so it looks like a real fire.
Although, this is a pretty cool image.
its nice. i hate telling everyone this but shouldn’t the flaming pumpkin’s flame have some effect on the environment? if its a screen it should also light it up. also, your character needs better clothing desing and the leg on the right side of image is wayy too straight. like no joints in that area or what? and the sweater and stuff is like super long and there should be more designs and spooky season related stuff right? and i don’t get the background in the gfx, and it really looks like he’s in some weird rooms with screen all around him:
(it kind of extends around the image)
and then the podium he’s on is kind of weird too then
i can’t see thepumpkin flame well on the reflection of the podium (you forgot to add the flame in the reflection)
and then its like a screen, but then it comes onto another stage that has more shadows and is not at all affected by the screen light.
Looks insane! Happy Halloween.
