Meganium: A Sauropod, with modifications. The flower was originally based on a Hibiscus or Geranium, but turned out just to be your average flower. You know, petals and shit.
Sceptile: My favourite of the grass lads, this guy was based on a Dilophosaurus fused with the Green Iguana. The tail was based on your average pine trees, and the nodules on its back are similar to rhizobia.
Torterra: The legs and shell shape of shape of a Galapagos Tortoise. The body shape is more Anklyosaur like. And the head of aSnapping Turtle. Also, Galapagos Tortoises tend to have their feet facing inwards a bit, so that's not me snapping its wrist.
This is just how I see these guys, and I understand if you view them differently They're really quite fun to draw, but I'm off to bed now! Hope you like them r/pokemon!
Torterra and Superior are my favorites.
Awesome job and observation on these!
