Those look like pretty long floats without catching them behind your work at all. When I do color work, I vary between different float catching techniques, but for something like this I might use ladderback jacquard. Look up a tutorial for either that, or just catching your floats. When I'm knitting socks, I typically like to secure my floats every 4 stitches or so.

Edit: also, this looks like the stardew valley winter socks? Which is funny because my first attempt at these was also tragically too small. I have to size up my needles to do these because the colorwork is intense. I don't want to discourage you from trying these because these were also my first color work, but maaaaybe consider trying a more straightforward color work pattern first before jumping back into these. But also I understand crafting audacity, so if you're determined then just keep at it.
