I did these a few days ago

Is it just me or are the projects in "keys to drawing" by bert dodsen waaay above the skill level of what it teaches you,like...you know some basics,now draw this fucking portret ,emulate kathe Kollwitz s portrait (atleast Delacroix was easy and pleasant) ,I know its suppose to get you out of your comfort zone,but not to the point where I m failing like crazy.I ve been drawing for a week ,studying this book. This is one of my drawings, and I guess is decent for someone who se been drawing for a week, but free handing a vase of flowers and ending up not looking like any kind of vase with flowers I ever seen crushes my spirit, Am I suppose to just power trough it or just try and try and try until it looks okay, that doesn't seem that practical either ,because for example ,the "draw your eyes" project was like the 3rd or 4th project and I could barerly draw an apple but he was expecting me to draw eyes so I just drew my fucking eyes for 3 days straight until I realise I need glasses.What Am I
