What size was the original RAW? Because the clean looks very very blurry, which makes the text look very sharp. What you might want to do is give it a little bit of a smart sharpen to help just give a bit more detail to the clean, as the whole image looks very messy as you kinda strain your eyes to make it seem more in focus.
Then again, with some of the older series and their RAWs, they can be at this kind of quality, so try your best and see if you can get your hands on some better ones, the better the original RAW, the better the overall clean. Do you mind uploading the original RAW as well? Allows us to compare what you've done and give you a better critiques as well.
Keep experimenting, and definitely get your hands on some larger scale RAWs as well, keep it up!
