First off, such early blitz positions are best handled by knowing standard reference positions and then adjusting. This is exactly what Tim and Nack did. A similar standard reference position is 51S55AFC or, equivalently, 52S55A2C, which is a medium no double:

Now, back to the OP. Both Tim and Nack pointed out their adjustments compared to the reference position. I don't have much to add to those comments. An extra checker in the zone for blue is huge; a checker off the bar for white is also huge, but minus a checker off her 8pt is somewhat bad. Therefore, the OP is a bit worse for white as compared to the reference position, but not as much as to make it a double.
