Design issue caused poor soldering

Question: Below design caused cold joint at the pads which are connecting to the center big pad.

Red stands for soldermask layer, Blue is for copper layer.

Answer: Better to have soldermask ink between those GND pads and the center pad to avoid solder paste on GND pads to be pulled away.
