of course you are free in your creative choices. And it’s fun.
But you are using a one point perspective (You learn this later in the course).
It’s not a problem at all, creative freedom.
And to make it easy these challenges are more flat 2D drawings.
I just scetched it as it felt naturally. Wasnt even thinking of perspective. I guess it helped with imagination. Im more of a 3d kind of guy. This drawing is going to be hard for me. But its worth a shot. Shading is kinda fun
