Diamond Long Legs and Beady Long Legs renders

Hello there, all you blender artists! I am somewhat new here and would like to share some of my artwork with you all. I have rendered a Diamond Long Legs model here twice(I stuck with the more opaque render). I have also rendered a Beady Long Legs model, with a bump map and such. I used a HDR for lighting(pro lighting: skies. Heard of it?) with a transparent background/color/not visible to the camera. Let me know what you think of it, and maybe even provide a few helpful words, such as lighting techniques that have worked for you in the past. The Beady Long Legs is from a game, Pikmin, and the Diamond Long Legs I got from some inspiration from a user at pikmin fanon.
