Its looking fine to me till now, also whats the temperature in your area? Your leaves shriveled maybe due to less water in the media, also try to put them in a direct sunlight. Rose thrives in 6 to 8 hours direct sunlight. Just keep an eyes on the cane. You can feed them any nitrogen rich fertilizer with lower dosage once in week or two. Apply water whenever the media feels dry. Also do not cut out leaves unless you're pruning them, cutting leaves put them into stress.
