Sorry, I'm not feeling it. I'm not a fan of the render. Most people who use renders with someone smoking in it usually take advantage of the smoke by making a dark background and having fun of the smoke, but that's been done before and there's nothing wrong with doing something else. The effects are too random- the scan lines, the borders, the splatter, the black lines on the left, and the blue squiggly lines near his face. Combined, these make the sig look way too busy. The text doesn't really fit either, and if you can't fit in text without it looking weird, it's better not to have text at all. The lighting is also a bit obvious. It's not terrible though, considering you took a long break
too messy text sucks (no offence) and scanlines dont look good in the sig. need work on overall compo
