These looks beautiful :D
One can easily see how you developed yourself by just looking at your previous concepts. I admire the amount of hard work and dedication you show in your art. I can clearly see that you will achieve greatness. Also, I lack the words to express how much I'm glad that you are working on the 'happy' part of the forest. These pieces fit perfectly into your already beautiful art collection. I actually think these are one of your best and you should stick to the happy themes as you seem like you're made for them.
