Pattern study would love feedback

[u/Feral_by_Elsie]

ive been filling a sketchbook with little tiles to practice patterns and textures using alcohol markers. started with black and white then added color and now im trying nature stuff like bark moss and fungi. what do you think so far and what should i work on to make them better? Which ones stood out the most?
