The bottom line to this is that for what you are doing you have way too little space anyway.
You should be able to clone your C: to a bigger disk using something like Macrium Reflect. https://www.macrium.com/reflectfree This will allow you to clone your small C: to a larger disk that you can then use as your main C: drive. It will boot up without you having to do anything other than the clone operation and then physically swapping the two disks over. I Use Macrium a lot BUT the free version does have some limitations and very occasionally doesn't work. So if you do decide to go down that route make sure you have backed up ALL your important files.
As I have said for what you are doing, graphic design, you do not have any where near enough storage. you do need to buy much bigger disks and it may be a good idea to pay for some online storage that will guarantee not to lose your files. Unfortunately with electronics a multitude of disasters can and do happen even with stupidly expensive online storage facilities. BUT online storage do have multiple backup methods that, for you personally, to implement would be cost prohibitive I would think.
Hard drives are reasonably cheap these days even for big ones. External hard drives are easy to install and use. SSDs are much more reliable than mechanical, spinning disk, hard drives. They are more expensive but they are coming down in price and getting bigger.
