Yep, the fire also reminds me, but just a little bit, of this one
reminds me a lot of this piece.
i agree with D-jinn that it looks unfinished in a lot of areas
many things looks unfinished, like the hotair-baloon. even the piece looks awesome for me.
just give you a try, and put some shades on it.
What D-Jinn said. I hope you will edit this and some shades to the balloon like you did for the roof.
