Wow, that's some really nice artwork! Although...there is a way to use the IMG function (that looks like a little Mona Lisa icon when you're making a post) so that the images directly show up here in the forum. That way, we don't have to be linked away from site. I say that because the shortened links you use are very sketchy and other members may believe there to be a virus behind them. Honestly, if it weren't for Toxic commenting and confirming that it was art, I wouldn't have dared to click them.
I understand if it's a reposting issue from the artist, but in that case it may be more to your favor to start posting the end of the manga that you're working on instead of what they're doing. At least for now.
But, as for the IMG function, you don't have to save and re-upload the image. You can still use the deviantArt link of the image only, so it in no way should actually infringe any copyright law, since you are crediting your artist in your main post.
