Help With PLA settings
It looks like your nozzle is a little too close to the bed, if there is not enough space, you can see through the layer and pressure can build up and ooze out when there is a little more room in a different location (if the bed isn't completely flat/straight).
You could level with a thicker piece of paper or add a Z-offset to the whole print ( e.g. in your slicer, or change the G-code by redefining the Z height).
You could also increase the first layer a little when slicing.
