What is the name of your pattern and designer?
It looks like this is due to the yarn and it’s not you. Your knitting looks nice and even.
It may be that although you can knit this yarn to the pattern gauge, it’s going to be a bit loose and drapey. It also looks like a blown yarn which tends to be softer and more pliable.
You could go down in needle size to tighten up the knitting but then you would not be on gauge for your pattern.
If you really don’t want the current knit fabric, you could try some swatches on smaller size needles till you find a knit fabric that you do like, then look for a pattern in that gauge. The other possibility is to keep your pattern but look for another yarn. The current yarn could be saved for another project.
Your knitting so far looks lovely.
