v3 is wayyyy too plain. The other 2 aren't blended at all and there is a huge difference in color between the render and the background
keep working on v1, the effects around the render are working, maybe move the render to the middle, and just create some BG on the sides
Yeah work with V1, im liking the effects so far, V3 is terrible dont go any further with that lol. but yeah, looks good so far for V1
V4 just added give cnc on it please I changed color of render to fit a little better with colors, moved him to the middle, and tried to create a bit more with the background..
you over did it with the grunge brush on the face of the render. and something needs to be done about the shoulder that is in the front. but you have a good thing goign here keep working with it.
