So I just finished my second GFX since starting a couple days ago!
About this graphic: Fan Art for a game on Roblox called “Witching Hour”.
If you would like to see my first GFX here’s a link to that: Searching for feedback on first GFX

I create GFXs for 1 year, and I can tell you that for a beginner, that is pretty nice.
You could just improve your lighting ( Don’t just use octace, improve yourself, octane would just make everything for you ), I would tell you to texture every single part of your GFX.
At all, I would say that your GFX is an 5/10. And that is pretty nice for a beginner.
Oh I don’t use Octane Render, I use Blender 2.8. Also the lighting being dark was intentional, it’s sorta the aesthetic of the game.
I like that you have the idea for action scenes, all it needs is a little bit of overlays and a bit of motion blur (not too dramatic) to finish this off. It will look super cool 
I honestly love it! It’s very good!
Though, the lighting sorta makes the players look claylike. Maybe just tone the reflectence down a bit so it doesn’t look like light reflecting from a metal object’s surface.
But other than that, very good work!
Really nice gfx, this is just amazing for a beginner. Keep going on man. 
It looks alright, but you need to add a focal point. When I see this, I don’t know where to look first, and it confuses me. I should look straight at a certain thing before looking around it!
