Floating city afar

Another fan art using soft pastels.
Oh boy, I'm having so fun playing with pastels. 
It's like my 5 time using my soft pastels. The last time I used pastels when I was like 10 and it was an outside of school art class. 

But it anyway it was an idea from the 2009 movie, where Astro is floating with the metro city in the distances. Expet Astro was wearing clothes at that sence :-3 but my picture I just do the same Astro's look.

but it it looks lie the city is on fire or some distraction, but it's not, I just accentually smutch the pastel and end up looking like smoke from the city >.<" noooooo"
