first of all, not a tag this should probably go into large artwork secondly, looks half-decent, but I'd make the girl on the left not that transparent, and I probably wouldn't have such a sharp line between both sides of the boy (unless that was the render^^) Try sticking to one single lightsource, and seriously, splattered letters look awkward never splatter that much above your main focal render... (talking about the splattered text above his legs) I've never really criticized LP, so you would get way more specific answers there
The line in between him definitely needs to go....It is way monotone, and it doesn't have enough contrast. There are too many people in the piece overall. Mainly in large pieces you want to focus on one thing, and if you want more, blend them in with the main person. The girl on the left totally throws off the focal point, which is the guy in the center. Your lighting is on the wrong side, and your texts shadow is WAY too far away. ^^ Now that is harsh criticism.
