do you think you can draw an elven city next?
If you want some inspiration I would suggest you to search on elven cities from the first age of Lord of The Rings. Gondolin, Alqualonde, Nargothrond, Doriath, Tirion,...
Also the warcraft elven cities like Silvermoon, Suramar and Zin Azshari
or Lux Aurea from The Dragon Prince
and there is also this elven city atop a volcano https://www.reddit.com/r/HighElvesHalls/comments/k9tw42/oroboria_the_citadel_of_the_red_elves_from_the/
also little sidenote if you want a good webcomic to read before sleeping or whatever I suggest you Drowtales http://drowtales.com/
I love the oranges and reds which arrive in autumn, and you managed to capture them very well in this sketch.
Even as a sketch, I can clearly discern the environment. You seem to have used the orange leaves strategically to provide dynamic eye movement with them, which I appreciated. The 'structure' at the right side works well as a focal point, and the 'star' inside it is what my eyes were drawn to.
Overall, nice sketch man
