good grid, only sour note was that "astrological symbols" not accepted

The red group confuses me - one is the "name" and the other 3 are "descriptions" - C_____ might have been better as G___? Even so this is a good grid, solvable and the connections were clear.

Liked this, thanks.

there is no 'Red' group. the colour depends on which order you solve them. (the red group is the third group to be solved) Also out of curiosity, what do mean by the C___ might've been better as G____? I know you're trying to avoid spoilers but its not clear!

Probably needed to use zodiac rather than astrological but I awarded myself full marks anyway ;-)
Fun grid

Capricorn does not fit with the other three in its group.

Goat would of fitted better than Capricorn, but I see what you were trying to do with crossovers
good grid

Really nice overall! Mostly echoing what has been said; a couple of the clever groups mix two types of connections together, which makes it messier than it needs be. Pick only one of "has a" or "is a" or "is named" for each group, and it will all come together splendidly.

We liked the Sting connection. It was the only part we didn't get! Very Good!

Very enjoyable, not too hard. Especially liked the 'bee' group.
