the blur on the end of the rockets works in shifting focus to the center, but overall i don't think the colours are right, especially with a dark background. If your having ridiculously limey and oversaturated colours, you need a pretty bright background with a high exposure, but if your having a plain dark background, you need more subtle colours.
Yeah, okay, try to make the focal much more defined and sharpened. So, I'd do the blurring again, also, it looks like it's stretched. As Matty said, the colors just look freaky.
your depth works pretty well, but your text doesnt go along with the rocket barrel. also, please don't colour the visor! i dont get why people do it, a green visor isnt normal! lol
Slanting text barely looks good IMO. Nice try on depth, but try to sharpen the focal a bit more. I don't see a light source. If there isn't any, then add one
I tried some other colors and they just didn't look right at all. Darker colors blend in too much and I want to make the spartan stick out. I didn't stretch it, but I'll work on that. Should I relocate the text? The light source is in the top right.
either relocate the text or make it go better alongside the barrel.. right now it looks like its not slanted enough
