No problem! One thing I would say is that when they'll look at your work they might feel you're not being original, they like to see your OWN character designs and stuff drawn from life and not photos. Every piece I had they asked me, is this your friend/from a photo/from a class? And I answered photo for one which I could tell they weren't happy with that! Everything else was from imagination/friends and they really liked that.
The 90s figure drawings, WOW, trust me when I tell you that people at your level of drawing will not get the full figure on the paper in even 2 minutes let alone one and a half. Thats pretty good!
You are focusing toooo much on details though. The purpose of such short poses is to get the gesture and movement rather than anatomy and proportion. Your sketches feel more like 3-5minute poses, since you're not really getting the gesture in there.
http://www.amazon.co.uk/Force-Dynamic-Drawing-Animators-Series/dp/0240808452 ^ that is an AWESOME book that explains it all, I got loads from reading it!
For your digital, I'm just guessing that you don't have a tablet? Apart from that, the most obvious thing that jumps out is that they are all kinda flat and don't have a light source. If I were you I would definitely spend some time to study values!
Hope that helps you! <3
