Watercolor practice

Recently I've been making cards for people for fun/ for people who give me stuff.  It's just so fun to do something that's not school related and so relaxing.  I think I'm going to get started on the holiday seasons cards soon :]  Here's a little Halloween one I did and a thank you card for my cousin who gave me a buncha persimmons.  The thank you card turned out to look more like tomatos though... 

Also, we ended up carving this guy in real life- what made it all the more special was that it was my first ever pumpkin carving!  It was fantastic.

My friend who is also an illustration major took a look at my other Halloween watercolors and said that I should try to be more precise with my coloring so with this thank you card I attempted that.  Did it work?
