For larger pieces of work, using a camera is still going to be more convenient. The main thing to note is to make sure you have proper even lighting.
Your 3-in-1 scanner is for scanning office documents, not for scanning art or photos, which is why the scan quality is not good.
Unfortunately if you want go go with CIS scanners, you'll still have the problem of blurry images when the paper is not in contact with the surface.
Your artwork is huge. Stitching together multiple pieces after scanning is going to be a lot of work. And you have to make sure you get the proper alignment for each scan before you stitch which makes it even more challenging.
You may be able to find some tutorials on Youtube on how to photography artworks or watercolour paintings.
