Skin Idea: Rogue/Rugged Poppy. (Based off of Frodo Baggins of LotR)
One thing that i've attributed to Poppy since the rework was her uncanny reminder to me of Frodo Baggins. Small, self-guided and ultimately an unsuspecting weight thrusted upon her even if she is unaware of it however despite her hardships and despite the many trials and errors she has run across and will undoubtedly continue to do so she still presses forward with resolve to finish her mission.
Humble, friendly and would rather make friends than fight.
Not to mention her own theme seems to be very similar to the soundtracks of the LotR movies.
I don't have any drawing for I can't draw but I just wanted to post this idea and to say that I would love to see how Poppy was before she took up the mantle of Keeper of the Hammer.
Perhaps Blacksmith Poppy already fills this niche but I was honestly envisioning a more civilian and cloak type of wear similar to what Frodo wears throughout his adventures.
P.S. Playing LotR soundtracks while playing Poppy is all too fitting for me.
P.S.S. Playing Breaking of the Fellowship when you go support Poppy is all too perfect. It's epic and slow pace reminds you of yourself and how you're a walking paragon of protection for your adc. It's lyrics remind you that you will die for your team and ADC eventually but it's for the greater good. The title reminds you of the fact that your ADC will probably rage and curse you out for not picking Leona instead.
