Looks like a great start! You're certainly getting into some good close positions and getting clear sharp shots (where the scenery allows you to). Shots 3 and 2 would likely benefit from a lower angle of view - if possible looking at eye level to the animals eye or looking up to them is ideal since when you look "down" on a subject its a more normal view for our eyes on most animals so its "something we've seen before". Getting eye level or lower presents a new angle and makes for a more interesting choice most of the time (though of course like most guide lines this is not set in stone).
Keep at it and have a look at the works of other wildlife photographers - take inspiration from how they've composed and captured their photos and see how you go as you develop your own style.
