/ic/ - Artwork/Critique

>start with Dynamic Sketching
>starts easy with line exercises, organic forms, organic forms, form intersections
>speed picks up, but still manage to do everything
>Next topic is plants, drawing from life, do the homework and enjoy it
>last video of DS he suddenly draws a tank and a giraffe out of nowhere
>difficulty skyrockets out of nowhere
I then jumped to Dynamic Sketching 2
>first video is a repetition of DS 1
>second video he's introducing insects
>pic related, basically draw the rest of the fucking owl
>difficulty skyrockets
So should I grind insects or look for another course/book?
