Hey there. So you're going for something between the left and right versions of your source?
Some general crits are: color, try shifting everything towards red a little + desaturating. Also this would be one of the few cases where lower contrast would help. Wood help.
Okay so if you study your reference notice the base tone is accented with essentially 1 dark and 1 light. My recommendation is to recreate that for the sake of study, understand why it works.
There's waay too much grain going on with your planks. Yes of course if we look at hardwood floor, we can see much variation, good contrast etc, but consider: if we compress that into pixels, information must be lost.
It's a lossy compression. And so you can't have all that detail anymore, you have to make compromises.
Your ref is a good example. There's just enough variation to be like "hey, this is wood and it has grain" but it's made with controlled, deliberate strokes.
Look at how each stroke flows into another, they touch but don't line up (save one which should be corrected). This is essential, as it avoids unnecessary noise.
Look at the low range of contrast between grains and the base color (again, because we can't fit detail) and the higher contrast which separates planks, and the highlights which help individualize them.
