Puzzle #52 - Competition Fivecells

My competition set for WAPC Part 2 (see previous post) for details) consisted of a Fivecells, a Fivecells variant, a LITS, and a LITS variant. I've always enjoyed region division types and shading puzzles, and LITS a favorite even within that subtype.

The theme here is fairly obvious and I enjoyed constructing this quite a bit.
