Not too bad for a first attempt. Here's a couple of pointers:
Animated GIF's are bad in 9/10 cases. Try to use them sparingly. That animated back button in particular is extremely jarring.
Try to keep your font styles consistent, you have three distinct pieces of text on the page and none of them look the same, especially as you've used two kind of 'handwriting' style fonts, along with times new roman, a much more formal looking font.
Other than that, the minimalist design is definitely a good start, as it's easy to see what it does and doesn't look crowded.
