Digital art: a series

Hello!!! I am a designer trying to niche down before I graduate college in the next year. I recently made the purchase of an iPad and fell in love with digital illustration. This is something I can see myself continuing for the rest of my life. Now that being said, I am very new to this and I can use all the help I can get! Do you have any criticism for me? I would love some feedback! 

I have posted these 8 x 10 prints on my Etsy shop which is linked

Thank you for your support!
