I'm still learning, and I want to be able to look back on previous examples, but I also don't want to needlessly spam the oekaki boards.

hYpothetically, if i were to make off-oekaki color-ins of this image to track progress and ask for feedback from other artists so i can improve and/or learn horse tips, where would that be? i could have sworn there were off-oekaki boards somewhere, but i'm either mistaken or blind.

i have loads of horse questions, and i'm in search of good references so i can learn.
i think my knowledge is being limited by google images. xD because according to them, this is a blue roan but also a silver black roan soemtimes? i know that can't be right, but i also know different breeds have different names for the same colors.

am i bottlenecking my knowledge by using lines that don't really have manes? are manes + tails vital for learning horse genetics?
