I'd just keep knitting. The extra yarn will work itself into the stitches beside it and even out when you wash or block it. The sts on the right needle seem a little smallish anyway.
Some of your stitches seem twisted, especially those on the L needle. Did the pattern say to work some through the back loop? If not, watch how you wrap the yarn or knit into the stitches. If you always knit into the leg closest to the tip they'll be straight.
