That is one intimidating foot soldier. Fearsome effects.
Not sure what to say about this. Can I see the original stock or render?
The soft brushing or bubble c4ds look out of place and don't really suit.
I see there is no text
probaly a good thing.
But yeah need see the render / stock to comment more.
Ok then I like the colour tone and the background does look good.
But I don't know, it looks like it has alot of potential, the background does need something else done to it but I'm not sure what.
Maybe blur some meteorites in the background or something. It would add more to the depth too.
