Toned paper is the best, and your drawings looks awesome! The only thing I could say is that the 2nd pear is missing a little bit of shadow below it, but since you did it better on the 3rd one I guess you already know it! :)

The second pair looks better, definitely. I bet if you did it a third time it would be even better! (And I see a missing line on the left boot heel 🙊)

I'd try to darken a little bit the light side to increase the contrast between that and the highlight :)

The gesture on the seal at the bottom on the second page looks great!

That's hard and I think pretty much everyone here has felt it, for sure. If you're in a place with that where you want suggestions for solutions, try starting your drawing session with an easy win. Draw something that has no rules but that you like drawing. Like how the Swordtember drawing challenge worked. There's no anatomy to worry about and some wonky lines are totally okay! And WHATEVER YOU DO, don't make yourself have to draw your greatest thing ever when you do sit down and feel like drawing., Those of us who can't find the inspiration to really draw something can do that to ourselves and out too much pressure on it. Make it a habit to draw a little and that stacks over time :D Good luck with finding your way to drawing more often!
