Unfortunately, I'm not familiar with Figes' books in general, but with a few searches I came up with a few reviews. The first, on the LRB, is quite positive, but the author, Geoffrey Wheatcroft does not seem to have, based on his wikipedia page, much expertise on the topic. The other, published in Victorian Studies, is more academic, and is quite negative. The author, Andrew Lambert, cites numerous errors. His most important critique is that this book narrates what he calls the "old-crimean war", and that it largely ignores what are now considered some very important aspects of the war. If you want some alternative books, consider taking a look at this thread (https://www.reddit.com/r/AskHistorians/comments/5v7ggr/what_...), where u/kieslowskifan, a user who I absolutely admire for his knowledge, recommends a few crimean war books to a fellow redditor. Happy reading!
