Nice one. It took me only one small guess to solve it.

Same. Once I'd completed all the color logic, I had to guess a bit, to keep going.

She looks a bit like a Disney anthropomorphic dog. Like, if Lucy appeared as a character on Chip & Dale's Rescue Rangers. ;)

Also did some guessing. Cute picture.

I like it! Really tough solve. I found some hidden color logic and one instance of EL, but still had to guess a bit.

Found to be solvable with moderate lookahead by wombatilim.

Initial line & color logic completes 59% with only black remaining.

R28: If R7-8 are black, the 2 in R27 needs to be in C5-6. This makes R29 invalid, so R28 C7-8 are white.

R28: EL marks C1 white. Minimal LL.

C4: The black in R28 will start the 2 in either R7 or in R29. Either of those will make R23C6 black. LL.

C6: A black needs to be placed in one of R16-18. Any of these will make R23C10 black. LL.

C6: LL from the previous step narrowed the options to R17-18. Either of these will make R24C10 black. LL.

C5: If there is a 2 in R17-18, C6 is invalid. Therefore the 2s must be in R20-22 and R26-29. R21C5 can be marked black. LL.

C2: If the black 2 is in R17-18, C6 is invalid, so these squares are white.

C11: The black 2 can’t be in R17-18 or C6 is invalid. Either R19 or R25-26 is black. If R19 is black, R25C10 is black. If R25-26 are black, R19C10 is black. Either one completes R19 and R25, so R19 C8-9 and C12 are white, and R25 C1-3, C8-9, and C12 are white.

C12: If R22 is black, R20 C4-5 and R21 C2-4 would be black. The 2 in C2 would need to go into R20, which makes R20 invalid. Therefore R18C12 is black instead.

LL to finish.

I wondered what was going on with the tree with the red leaves and the black berries, and the little pond, and voila! Lucy appeared! Same issue with the final black solve.

For me, there were too many lookahead steps that required much searching to find, and which each yielded minimal advancement. While each one may be "moderate" I would consider the quantity of un-obvious lookaheads as rating "deep". I'm afraid it wasn't really enjoyable for me, although it's a great image. Kudos to Wombat for figuring all of that out!
