I think this is sort of helpful lol. I think it's interesting to note that the original and Thalia's copy are exactly the same down to the sketch marks. The loss in quality between Thalia's and the original is due to sizing; it only took me a few moments to change Thalia's to match up to the original, found here:

It's also interesting to note that Thalia changed the order of the individual sketches and erased the numbers next to them to try to decieve other users. If you look closely and change some contrast settings, you can actually see where the circled numbers of the original were erased.
Not that it really matters, since Thalia 'was hacked,' but I thought it would really demonstrate the effort put into decieving a normal user. Thank goodness Hj asked about this, otherwise other Rescreatu users could have been decieved. ;D
