We actually seem quite similar, switching between intense figure drawing (though no such class exists in my LOLCATHOLIC high school, hence I improvise) and cling to the wonders of comic/fan/smexy anime art. The man life drawing and the last funny drawing are some of my favorites (though I like your knack for mecha as well). His pectorals could use a bit rounding out, with less harsh shading, but less white around the beginning of the shadow.
Sorry to comment on your older stuff, but I really liked it.
And your future improvements are very noticeable too.
Glad you're apllying to Ringling.^^
