I neglected to mention...
Those little critters are really cute. I don't recall ever seeing them before.
I love how they suggest there is more of their story to tell, just outside the realm of this illustration.
And here I don't use the word 'illustration' lightly (pun intended!). I'm captivated by how you have illuminated the characters and their activity with fun shapes and detail.
My primary suggestion (not that you are looking to change anything) would be to make the letters of 'show and tell' on the board a bit larger as they are hard to read. I suppose an alternative to that would be to make the color of the letter contrast that of the blocks they are cut into (as if paint had been applied to them). Of course the small size does suggest that 'Haven' is using found items and use what was available... tiny scrabble-sized blocks with letters.
