don't be
there are dark edge on the bottom
and the left edge have something weird i couldn't blend (download and zoom)

watch my other tiles
and u will see the way i blend
when borders are ok

see ya

Yeah, I've seen your other tiles and I know your blending is usually pixel-perfect.
Oh well.

Sure, you got a "dark edge on bottom", and sure, most miscolored border spots are accidental, but I really don't think this one was. In this case, I'd say you should have continued what the dark spot suggested -- that the left part of the blue shape was spherical instead of oblong. Not everything in your tile should have to look like it continues an inch past your border for your neighbors to blend your tile well.

And, what happened to the left edge? Dark line? If so, you should have just ignored it and blended from the rest of the shape.

yeah, you can't really get spherical with a horizontal line

good tile. the bottom is not very good
