Puzzle Description:

Redesigned Union Jack with the Welsh flag.

The symmetrical lookahead in the upper left (c1r6 knocked a whole bunch of others off) was interesting--the Scottish X was solvable with line/color logic, but the inverted one wasn't. A neat image and use of colors.

Initial line & color logic solves 88% with only red remaining.

If you extend any of the remaining red 6s to the edge of the available area, it will make a 6 on a 90 degree rotation invalid. LL to finish from there.

Found to be solvable with moderate lookahead by wombatilim.
