Trenyce's Birthday Cake

I didn't know where I get the courage to attempt a birthday cake for Trenyce's 5th birthday. I did ask her which character she like, and she told me she likes Dora the Explorer. It took me quite a while to hunt all the Dora characters, manage to find 1 board game with almost all the characters in it.
As I didn't attend any cake decorating class before, I just collect some ideas from cakes selling at cake shops and ask my friend S for advise on some cake decorating tips. The cake turn out not so well done as my piping was really lousy and it took me quite a while to apply the layer of cream for the base.
