Sentiment vs. Storage

So I have a question for you guys. I've been going through a ton of stuff getting ready for the arrival of Miss Olivia and have come across gobs of stuff we've moved from place to place but never pull out or use. I am not a sentimental person at all so I sometimes have a hard time finding that fine line between keep and just toss it.

I came across my old drawings for school and I have a couple that were my favorites and are framed and sitting in storage :/ but I don't know what to do with the rest. I took pictures of them so I could throw them away because they've been sitting in the closet. Should I throw them out? I have really no use for them at all.

(It keeps uploading this one sideways) But I have tons of misc. stuff. I have ink drawings, chalk drawings, fashion boards, projects.

This one was for a final project where I had to come up with wait staff uniforms for a restaurant.

I remember my hand cramping so bad with this project. This I had to paint this with liquid ink with a teeny tiny paintbrush.

This was another final project where you had to paint the same image in all the different color scales.
I don't know what to do, I had totally made up my mind to throw them out but now I don't know. They don't serve a purpose. Do you think taking pictures of them is good enough to keep the memory? Thoughts?
