Well, honestly, I'm never one for long renders, and long renders don't always equal a great work of art... However, whether this pic took you 10 minutes or 14 hours, it looks great.. :) I guess the only thing would be to have the plane a little more banged up, but that's not a big deal... I don't know what setting you used for rendering, but it's a good quality.. I imagine whatever material you used for the fire is what took so long to render, cause it doesn't seem like you have a lot of stuff in the scene... Maybe you rendered to 300 dpi.. I don't know.. But it looks great and in all the time I've been here, I've never seen anybody do 3 entries for a challenge, so you're way ahead of the pack.. :)
