I think it's time you tone down your attitude and rethink your use of these forums, man.
Okay, see how the one piece you've posted so far isn't that good (honestly, not to be mean)? Well, you know how, I dunno, people have a tendency to sometimes lie? It's an easy conclusion to come to - even if it ends up being wrong - that you haven't got as much experience as you say you do, especially since you haven't proven anyone otherwise aside from arguing that you are. As for 3d translating to 2d, if you majored in 3d art then you should have learned the fundamentals of art in general, including, no, especially things like perspective. You know, horizon lines, vanishing points and all that jazz? That stuff was meant to make the application of 3d space in a 2d plane such as pixel art easier, rather than, I dunno, winging it. This may be a practice piece but that doesn't mean you have to get all indignant when your the one too busy defending your word choices and refering people to the original post. This is an art forum, not a game forum. We see art, we post what we think needs fixed. Chances are the longer your initial post the less people want to read it. We assume you came here to get critiques, so if you've got anything pertaining to the art to be said, go ahead, but all that extra information about the context and origins and game is just, well, pointless. This is not a game project forum. So, then, when people continually tell you the same thing is wrong, then it apparently means you haven't gotten around to fixing it, which maybe means you won't, which would mean you're ignoring valuable information.
Don't get flustered when all you have to do is either take the advice or leave it, update, and repeat. No one here is really anticipating your next iteration, so no need to announce it. Just post it when you need more help or when you're satisfied or when you think it would be a good place to start.
Okay, sorry if I misunderstood something, and Hawk, I wish you the best of luck with your endeavor. Just...chill.
