sburns the front of the seat is way too high IMO, I am getting pain just looking at the side pic . Ideally you want ~level when riding (your weight on the bike), if the bike is rigid just make it level, if it has a front suspension fork you may need to make a very minor adjustment to compensate for suspension sag. The post to seat mount should (will) allow you to adjust angle and front to back on the same mechanism. When loose the seat can slide front to back on the seat rails and the mount should have some rotation ability for level. It looks like it has the "older style", just a post and then a separate seat mount clamp, they can be a bit of a pain to adjust. I would focus on knee angle (height) and level if you can't get the shin bone directly above the pedal axle, get it as close as reasonable. Many times you may actualy need a different seat post with a higher rear offset to get that seat front to back dialed in perfect. Specially if the frame is on the small side for the rider.
As for the seat, sure it is a cheaper one but at the same time I see nothing in its overall shape (pretty generic middle of the road) that should be a problem for the average male rider not doing super long rides. But as others noted, there are a tonne of shapes to get that dialed right in if need be. I prefer trying to dial in what is there best before throwing money and/or parts at the bike...
