Just because you can pass it off doesn't make it right. Most of the time you don't see knots on 3D trees because they are very skinny... a knot would be very fitting for this style of tree. Because 3D objects are often rotated, it also wouldn't look that repetitive.
I also don't think this is very anime-style at all... looks very... painted, more than anything.
