In the interest of sparking some discussion/direction thought I'd share one of my early theories. Might help others eliminate solutions.

So to me its clear that the solution from the address is to do with a value (either raw or hashed with SHA-256) that exists in the flames. No big revelations. As mentioned its a vanity address so the private key will be random and wont conform to words/brain seed for priv key.

While there's a lot of noise going on in this image I feel some crucial elements get overlooked, so I try and find approaches that incorporate definite cues. One of these I feel are the meanders (squiggly Versace snakey corner thingys).

I looked at sequences and mapped the eight 'sides' (4 inner, 4 outter) paths and sought to use the meanders or glyphs in the corners of the painting as directional starting from corners. I did this going Clockwise and Counter-Clockwise for a total of 16 'walks' from a corner to a corner

The binary values I took were the characteristics of the flames one at a time eg looking at length where long is 1, and then its inverse for a total of 6 sets (Long 1/0, Short 1/0, Red 1/0, Yellow 1/0)

The meanders  are either CW and CCW and interestingly appears four times but for this I just tested moving CW + CCW and moving CCW + CW for a total of two rotations around the flame path but avoided trying four 'rotations'  because too much.

Given that the meander has 7 sides (of the eight, you'll notice the last inner side is missing ) I took this to be a hint that the missing side could be an indicator to exclude a side from the sequence. Or two. Or none.

So for each meander I test 0 excluded, 1 excluded and 2 sides excluded ie. the none, one or both the right sides of the chess board arent in the sequence for the meander rotation. I'd also twist the meander, changing the sides that are/might be excluded.

To visualise picture the two meanders on the middle of the board. One would be either CW and CCW in direction. I'd start them both so the missing side would exclude the right. Then change the second one to point upwards, then left, then bottom. After one rotation I would change the first meander from the right to the up excluding position and repeat the seconds movements again.

There were other rules I included when starting a path and coming across excluded paths such as dropping to the inner path or skipping but no dice. Anyway might spark a lil summin summin for someone out there.

A big PSA as well Vitalik Buterin's github has some useful tools that will come in handy for converting  this convertin priv keys > wif > address to verify. Google PyBitcoinTools.
