That sounds a bit much for that size database, but it certainly doesn’t hurt anything. The log file can be maintained by setting the recovery model and implementing a backup schedule. In simple recovery model, the log file gets truncated automatically when you run a full backup. For all other recovery models you need to do a log backup to truncate it. If yu have this backup schedule in place, just leave the log file as it is. It might not be completely used but at least that way it won’t get fragmented.
