Not a bad effort! It's easy to understand what you are saying, even if it is a bit slow. Slow practice is good though, and your tones are fairly clear. The biggest problem is your "ou" sound in 狗 and 走. You are saying something that sounds like "gao" and "zao". 狗 sounds very like "go" in English.
The other issue is the 學 in 學校. Make sure you make it a second tone (that means rising more)
Keep working hard :)
