Embryonic Connective Tissue, Mesenchyme 40x

So you do have mesenchyme in your picture, but the L for lumen is put in a place that I don't think is the lumen, and the N you've labeled isn't a mesenchymal cell. Can you relabel this image, remove lumen (don't worry about it- you're not labeling epithelium) and label a mesenchymal nucleus, which you have at the top of the image? Other than that, you're good.
