Im taking a break from the Jock to move onto the cheerleader. With some knowledge of the problems I encountered doing the Jock, the modelling of the cheerleader has been altered a little, mainly with the clothing and arms. So far I have the basic shape / proportions. The concept exaggerated the thinness of the waist a lot more, but after looking at the Jock, I don't think that will animate too well (or rather, at this stage I don't think I can rig/ skin it well enough) so I'm going to try and make up for the lack of style on the waist with the chest and head.
The skirt is just a basic mesh at the moment, I'm going to add more detail, a trim and some offset to make it look more cloth-like. I was going to look into using N-cloth, which will prove to be another thing to read up on. The head is going to need quite a bit of work to get it looking nice.
I was thinking about reference some Pin-up girls for their natural traditional beauty. I caught an image of Audrey Hepburn baking a cake the other day and haven't been quite the same since, the image below show a sort of style I think would go well.
Below is the progress of my, not so appealing Cheerleader, but give it time, she doesn't even have a head yet.
Got the proportions of Elastigirl from The Incredibles.
She has the proportions of Elastigirl from The Incredibles. :D Is that what you're going for? If not, then I'd suggest bringing those hips in a tad.
