yes there is:

do you see that?, well, that is the user implying she drawed it free hand, with or without reference, when its clearly traced from that reference or a similar one(there are many, thats just one), thats 100% deceptive for if something is traced you will obviously respect the proportions of what you are tracing,
saying that you are not good with proportions but that it came out ok, is like saying its not traced, which is obviously a lie, additionally as you mention the source of the tracing is not atrributed, so its plagiarism.
In any case, thank you for your feedback.
