The issue I see here is that you made the classic mistake of spending a long time on texture details before you got feedback or self-evaluated your fundamentals (composition, shading, form, silhouette, etc.), and now that you are receiving good feedback you are unwilling to apply all of it. You will only improve slightly and your piece will always suffer because of this. I suggest you wrap it up and start a new tree, this time getting feedback along the way. I'm sure you will be much more pleased with the outcome of that next one.
