that's not what i mean when i said the beehives needed more detail. i meant you should make them stand out more. give them some light shading and darker outlining so that it not only goes with the whole tileset, but also that it stands out, making it easier for those who play your hack to recognize them.
here, i did a little touching up on the older screenshot with the honeycombs:
if you want to use those, feel free. i used all the colors that were already on tree and the honeycomb.
edit: also, you may want to consider using different sprites for the headbutt trees. they just don't look right =/... if that's something you'd want to consider, then you can always have me redesign a headbutt tree to look more... well, bushy? i don't do much overworld spriting, but i'd like to try...XD
