Your color, lighting, and linework are all done well. I'm not much of an anime-style type guy anymore, but I appreciate what you've done, and the resolution you did it in. I have a few suggestions that you can take or leave. First, when you upload an image to NG, I wouldn't upload it at its full resolution. At it's current size it doesn't fit anyones monitor, even if they had double the resolution of current displays - and it takes forever to load. Secondly, work on your perspective. The viewing angle is straight on, but the table and bookshelves look as if we're viewing at a downward angle. We shouldn't be able to see the top of the bookshelves, at least according to how the characters are positioned. Same with the table, though I like what you have arranged on it. The background is also askew slightly, which is interesting, but slightly disorienting. The way you do folds in clothing is a bit haptic and doesn't make much sense, especially in the dude on the left's left arm. I'd suggest googling dudes in dress shirts in various poses and you'll see they don't have those strange bulges and sharp folds that run down the upper arm like that. Also, grey-bro has a very effeminate hair-style, but that's neither here nor there. That's all I've got to say about that. Keep up the good work.
