Constructive criticism welcome

I do welcome constructive criticism.  Any suggestions on how I can improve on my work or do things differently are greatly appreciated.  Up until now I've been mostly learning by my mistakes, which I have found to be very helpful.  I tend to be a perfectionist, so it's difficult going through the process of making mistakes.  Watercolor is a very unforgiving medium, so I've had to learn to accept that the mistakes are just part of the process.
