Welcome to the void.
the render is really LG and i dont like there like LQ rings around the gun, also it all looks to over sharpend and the c4d doesnt fit, light source in the corner isnt strong enough and the text isnt needed, its a good start i gues if you have just started using photoshop, and i can see potential GJ mate and KIU and if you have any questions pm me or a member of staff
