I love the CG MC in this, and love the idea of GGGB being refreshed with CG art. Ashley is hot without being a perfect 10, which is congruent with the original art. Being honest, I like that this Ashley is busty.
Speaking of honesty, I don't have an issue with this dev re-making the exact same game with CG art and getting paid a little for creating that art, provided that they've received permission from Eva Kiss to do so. Or if this is a re-imagining of the original game and the story will diverge from the original, that's OK, but I think it should be made clear where the original content starts - and the first release should have had some of that original content in it (more than minor edits / omissions; I mean new scenes).
My suggestion would be to have the original story content in a Prologue, specifically labeled as backstory. The new content that diverges from the source game would start in Chapter 1, and that should be what is labeled as version 0.1.
