Nesgran has summed it up well, if you had charged someone to take these shots, you’d be guilty fauxography. But your site says you’re learning so fair do’s for asking.
You seem to have a fairly god eye for a shot, but your colour and gamma are letting you down badly. The first shot is so dark I hardly make out what it is. If you have a monitor set up for gaming or watching movies, it will be useless for judging exposure.
