Umm... still haven't shown the comparison. Sorry but as a fellow artist you're being overly egregious with your claim. If we're gonna measure with this same rule then EVERYBODY here is going to be held accountable for plagiarism. I've been here for years and every summer entry is extremely similar to previous ones. I can boil it down to like 3 thematics: summer night party, having fun in the beach and sometimes pool party. Everybody's entries are extremely similar when the thematic is about "summer".
Nobody owns a concept or a thematic. But here's a tip for you: claim for plagiarism is valid when the piece of artwork is so similar there's no creative input from the artist to obtain a different execution (of the same concept). The claim is usually used against traced art, stolen or copied from somewhere else with no credit attributed to the original.
2nd tip: Just beacuse someone else used Munak Hat and Poring in their entry doesn't mean the rest can't. They don't own the combination of subjects, that's ridiculous. If I were to measure with that same rule, then everybody drawing a human with summerwear/bikini is also plagiarism.
If you show me these are traced, copied or stolen. You have a point, otherwise your point holds no water.
PS: You still haven't told me how Veha's artwork is plagiarism. As far as I am concerned there's no similar pieces in this entire forum that say otherwise.
