A bit of an unusual story is behind this one. This was essentially plan B, for lack of a better term, since what the requester asked for originally was apparently out of my league. The weird thing is, it was a simple 5-character drawing, so considering I've worked with more, it shouldn't have been that difficult to get through. Oh well, this should make up for it.
So, from left to right, we have Winry Rockbell from Fullmetal Alchemist, Dawn from Pokemon (an older incarnation, for obvious reasons) and Ciel from Megaman Zero, all stripped, hogtied and gagged.
Despite the surprisingly short time it took me to draw this, there were a few things I wasn't used to. The biggest one was using actual perspective as opposed to having everything on a 2D plane, as well as creating references for all of their poses using Samus's model. I've done that before, but not to this extent. I was going to have them in heels as well, but I figured I should throw the feet lovers a bone for once.
