Yes, you are correct as the size of the continent also assists the animals and the insects to grow to bigger sizes. No, your photos are excellent and no need to feel that my photos are better.
That is one beautiful dragonfly and I have never seen one in those colors, but the wings tell me that it might be a Dropwing. Pity that I cannot see the torso, or the body as that would make it easier to identify its specie name. A lovely photo my friend.

Have some !Pizza lady Elena.
