Linda, I have to say that being so fresh out of the gate, you are doing fabulously. While there is so much too learn (that doesn't stop in case you were wondering
), I find it best to focus on one thing at a time instead of multiple letters. And the basic strokes are the best place to start. I know...they're boring. But they are worth it! The importance of being able to execute a perfectly straight line and oval is paramount. I would start with page upon pages of those. Throw in some 'u' and n' curves as well to get a feel of the pen as it turns. Another thing you might want to try is practicing in pencil to master form, then switch to pen to worry about shades. If you try to focus on too much at once, especially at the start, everything suffers and at best, progresses slowly.
That said, you are a natural. Your slant is consistent, as are your shades. Your ovals and some of your overturns are a little pointy with the turn often being a little lopsided with a rightward lean instead of being balanced in the center. This is really obvious in your run of them just before those y's on day 2. On that same page, careful that the prongs of the 'u' are not closer than the spacing at the bottom. The d'...I find the ovals a little too fat for the height of letter...which reminds me, Copperplate is usually a 3:2:3 ratio. The loops of the g's and j's are stunted (but the y's are good). I love your loop width of the y's. That should be the 'thickness' of your ovals (and of the underturns of those y's. They should be equal thickness (here the y's underturn is wider than your loop). Similarly, the u's and n's you practiced are wider than the running string just below them. I like the width of the running string, but find the individual letters a little too fat.
But definitely off to a fabulous start. A lot of the turning issues will come with time and many pages of drills, especially ovals
