Pride. Stop exhibiting your mansion around. It's not polite.
Sloth because you didn't show up to be evaluated. Stayed at home snoozing :D

Pride! (not your group of lions ;D)
You are a show off about your transformation skills.
...Is that even pride? I dunno!
Lust, you're not as innocent as you look

Pride.
Looks like you think you know it all because you go to a fancy college and brag to all your friends about how much smarter you are :p

Lust, and well... I don't think that one needs explaining XD

They´ve said this already, but lust. Those half-closed eyelids, that blush, those dark painted lips, that exposed belly piercing.....
Even your siganture gif :P
You perhaps might be onto something ;)
You look very envious of others to me... So we will go with envy!!!

Pride in your, what you believe to be, overwhelming knowledge

Of course this is just the story I've concocted in my head, but your sin would be greed. You look like one of those entrepreneurial fellas who sit around devising new episodes to Ghost Adventures at locations that aren't genuinely haunted, all to make a quick buck off the more gullible.
Wrath, someone did you wrong and you are going after them with that weapon and finish the job with a smile!! o.0
