Actually the truth is those are VERY good for beginner's drawings. You seem to have a natural understanding of proportion and expression, and that is a huge part of making a drawing look appealing and natural. In fact the foal's head particularly is lovely, expressive and life-like.
Keep drawing, keep observing and also look at other art work, what appeals to you, and see if you can understand how the artist achieved whatever it is you like about the picture. That's not cheating or copying, that's learning something and your technique will always be unique and your own.
don't worry, spiders, I keep house casually.
