Could you give at least a partial reconstruction, so we can see how you made the x-crossF2 U F' U R2 L' B2 U' F2 R U2 R' U2 B2 L' U2 L F2 R
Just got 12.29 with this, I average 19.5. 3 move x-cross on the b face with a corner and edge already paired for the second one.
For non blind this has some pretty good crosses, and I love how each cross has at least 2 pieces solved.F R' D' L2 D R B' L' F2 R2 B2 R2 U2 B R2 D2 F R2 L
7 edges solved, 2 edges flipped in place. Try this scramble if you like 3bld (I got it for 3x3 though). Edges solved in one 3 cycle! (depending on buffer) and then flipping the edges.
