Nice, did you render it? Maybe add some lights and effects, it will be more realistic
I think different clothes on the rig would be alot better as that sort of blur doesnt correlate with its high quality render. If more color coordination (orange on black instead if blue & pink) were there that’d be great as well. This ones also a smaller note but if you smooth rendered the background to help emphasize the texture it would make it cooler 
I recommend Using Cycles as your render cycles as it will be more light accurate than eevee. I would recommend using different clothing because the one on this looks like it’s made on microsoft paint, something that would match it. But the overall looks of it is really cool. It just need more adjustments.
Believe it or not I am using cycles but thanks for the info
This gfx is nice but there would be a couple things to change.
-
The backround is a little plain but good.
-
For the second thing im not sure but something is off but i cant tell what it is.
Very good job though!
Okay, so here’s what you need to improve or change
Sniper Rifle should be bigger
Work on posing
Change the background because it looks like you’ve just took a rock and size it up so it would fill the bg
Add overlays that helps to fill the emptiness and also it will enhance the looks
Would add a nice light to the pumpkin face so it looks like it’s glowing
Make the lighting better
Use different clothing because this one is in bad quality
