I disagree with rudeness of "Achore", but he does have a point.
I put them side by side, and I see that it's been clearly traced. 
There is nothing wrong with tracing imo, if you change the originally traced piece enough, which you haven't.
E: as someone who is new to art, i understand the value of tracing, but in your case... you don't need to trace. You're good already. But if you insist on tracing, then do it only for the initial sketch, and change the piece in the process, use it as a starting point instead of ending one. Well we all make mistakes, we just need to learn from them, hopefully you will learn from yours.
I liked the original character and the position so I got my own version, And you will find tons of similar characters on the same position on the internet never saw anyone complaining about it I think in this case is just that some fans of mgd are so passionate about it that when they think someone stole something from the game they get angry. When in reality is the opposite it just show that the characters in the game are remarkable enough to be remembered and for someone to want to create something similar.
She will get more positions later so it should solve the problem if there are more people like Achore.
Firstly if you thought that was rude, than I am sorry for that. I am in regards of communication... VERY direkt and just say what I think without any care of how can I say it nicer. Sorry for that.
If it is traced, mad respect to your skills, but than your tracing skills are... too good ;) Sure here it is just about an H-Game, but if it was an Character from something like Disney hell would break loose just from their and of things.
And from my point of view you were just in denial or sitting in your chair smiling and lying about the fact that these two artworks are too similiar to be a coincidence.
You did not just use that char as simple inspiration if they are similiar and the same on so many levels.
If you would at least say, yes I went overboard with my tracing/drawing skills this would be a whole other thing. The problem is not that these are too similar, the problem is you say these are completly different chars.
Edit: Finding chars/artworks/fanart on the internet is one thing. Using that for a game you want to earn money with is a different story ;)
well, think of it as artistic courtesy, it's fine if character is similar, but umm... please understand how it would feel for that artist to see this.. well it's not cool. There were ways to improve it and make it yours, but you skipped that part, and worst of all you put the screenshot of pretty memorable character on the front page. For a game that is essentially the same genre as the "inspired" character is from. Well, i'm not angry or anything, like i said, it's just not cool, and my point was and still is that you seem to be fully capable on doing it better on your own. You're clearly not a beginner when it comes to art, take your time with the art, especially if you're making a game of your own, don't cut corners on a art when it's the primary "bait" of the game.
I wish that you learn, improve and make a banger game. God knows indie games are the only hope that game have left.
