Looks fairly close to the textbook examples I have seen. Actually it looks extremely close.

Other less formal script is sometimes easier to read. Л и М with deeper initial stoke makes for easier reading, more like Greek mu and lambda. I make my и more sharp in the dip, to accentuate the difference from script u.

(I make my б more like old fashioned caps print, and I don't confuse it with Greek lower case delta, which is sometimes used in Cyrillic instead of the script you show. This type of curly delta you will sometimes see in википедия. One is almost the mirror image of the other.)
