OI! Not only heretical, but also plan ugly. The eyes are just creepy.
If there wasn't Holy Trinity depicted in such way, probably it would be acceptable:
No, there's more wrong with it. Adam and Eve being on top of the Earth, even if their posture is that of submission and humility, still suggests that they have dominion over the Earth, which is not the case. Also, the depiction of the dead Christ in the top of the image seems to suggest that Christ not in the same body as he was before the Crucifixion, and that he made a new body for himself for the sake of rising from the dead, and both bodies were assumed into heaven. Also notice how none of figures, not even the three figures intended to be the trinity, have a halo. Finally, there are figures at the bottom, that due to the number of wings I think are supposed to seraphim, are not displayed according to the canon, and neither are the 'cherubim' that are around the three trinitarian figures. They should look like this, with the seraphim colored red and the cherubim colored blue.
